This review is from : Lortone Deluxe 3A Rock Tumbler Kit
Lortone 3A . There are many varieties and brands of rock tumblers, and I selected the Lortone 3A kit because of its price and basic features that satisfied the purpose I had for it, namely, to polish some beach stones that the family had gathered some months ago. The kit contains a sample of jagged rocks if you'd like to start from "scratch", but the beach stones we gathered were already smoothed and rounded, so it is a matter of "finishing the job"! The Lortone 3A comes with a single good-sided rubber tumbling chamber with a four-step polishing system of abrasives. In our first attempt at polishing, we began with Step 3 because nature had already smoothed the beach stones to this level. Step 4 performed the final polish beautifully.A couple of things worth noting from our experience: Amazon did a fantastic job delivering the unit in a timely fashion. Also, please consider what you feel your needs are. There is a two-chamber model that might be more fun for your family because it allows for more polishing work! And please consider that each step in the polishing process requires a full week to ten days, possibly longer depending on the hardness of your stones. Nature cannot be rushed, and very few children will enjoy the agonizing wait. Even as an adult, it can be difficult to wait patiently, so perhaps rock tumblers are more of an industrial or jewelery-making machine and less of a "toy". But if you have some raw materials like interesting beach stones or what not, it may be worth the small investment in this tumbler (or one like it). We were able to leave it running in the garage for all polishing stages, and it worked tirelessly with minimal noise and completely free of messes or leaks. Good luck!

Lortone 3A Rock Tumbler . I am very happy with this. I didn't realize it was considered a toy, but if it is, I am enjoying playing with it! I've had it runnin 24/7 for the most part since I got it and I love it. It seems to be very durable and the process is really amazing. I look forward to working with my grandchildren on projects with this rock tumbler in the future. I see no reason why this exact one won't be in working order still at that point.
Lortone Deluxe 3A Rock Tumbler Kit Opinions
Rock Tumbler . My wife is a jeweler and has been interested in creating some of her own beads and settings. She has found this to be great to this end. It is sturdy and comes with enough polishing material to complete a lot of projects.

Cons Review
Excellent gift . Purchased this as an early Christmas gift, the instructions are well written, and easy to understand. The one thing (which I already knew) is that this does take at least a month for the finished product, and there are not enough beads for the last process. Other than that Love it!!!

This review is from : Elenco AC/DC Triple Output Power Supply Kit
Great Kit! Great Price! . This is an excellent kit. The quality of the components is high. The workmanship on the chassis is high. The documentation is excellent...includes many pictures, diagrams, theory of operation, check sheets, etc. This kit is sold in the Amazon toy store but it is NOT a toy...it IS a solid experimenter bench power supply. It is easy to assemble. It worked perfectly first time it was plugged in. I cannot verify the stated regulation or ripple specs (lack of proper test equipment and load cells at home). The only negative I have (and it isn't bad enough to reduce a five star rating) is the wiring of the regulator ICs and a power transistor is by direct soldering to the component leads...pretty low class. But it helps keep the kit cost low by eliminating sockets. Good soldering technique is required to accomplish this part properly.All-in-all a really good value and a lot of fun to assemble.
Elenco AC/DC Triple Output Power Supply Kit Reviews
A very good choice for the experimenter or hobbyist . While it isn't designed to compete with lab grade power supplies costing several hundred dollars, it works very well and should more than meet the needs of the average experimenter or hobbyist.I was going to add more filtering across the binding posts but after looking at the output under load with an oscilloscope and spectrum analyzer I see no need. The output is very clean and stable.While the construction is simple and straight forward, this kit does require good soldering and assembly skills. Mostly for wiring the binding posts and voltage regulators that mount to the heat sink. You need to free-hand solder wires to the leads of the binding posts and TO-220 regulators which takes a little experience and skill. Instructions are better than average with plenty of information about how the circuit works. The only trouble I encountered was a nut that didn't have any threads, which I replaced with one of my own. Other than that everything was there and it worked perfect when done. I put it together in an evening with many, many breaks. Total time actually working on it was probably 1-2 hrs.Bottom line, I'm happy and am comfortable recommending this power supply. I gave it 4 stars instead of 5 because of the wiring of the regulators on the heat sink.
Elenco AC/DC Triple Output Power Supply Kit Opinions
Definitely Not a Toy . This kit, at an unbeatable price for its functionality, is much more difficult to put together than I originally had expected. Wiring the terminal plugs is going to be an exercise of your engineering prowess and patience. Soldering the ICs will make you reconsider whether the makers of this unit know what they're doing. Also, the kit should have provided shrink tubing to protect the leads of the ICs from making accidental contact with one another, especially since they are potentially reachable from outside the enclosure.

The circuit board itself is well made and outlines the polarity of diodes and the electrolytic capacitors. The instruction booklet details the process of soldering and explains the circuit quite well. It however, falls short on the order of the instructions. If I were to go back and assemble this kit again, I'd have made significant changes to the order in which parts are assembled/soldered. I'm not convinced Elenco did a check to see that someone who hasn't designed/assembled this kit could follow the instructions to the letter without issues.

***Pros***

Really Good Price Point
-----------------------
Most of my purchasing decision relied on this basic measurement: is it worth it at this price? The answer: yes

Positive and Negative Rails
---------------------------
When working with OpAmps, it's great to have a negative rail integrated into your power supply. Other kits at this price range did not have this.

AC and DC Power
---------------
I haven't found many other power supplies providing both AC and DC power as a kit in this price range (on Amazon).

***Cons***

Hard to Assemble
----------------
Terminal plugs are not solderable, this means you will be working in a confined space to wrench a wire in between to very small nuts on a peg, 7 times

Inefficient
-----------
The supply makes use of linear regulators instead of switch mode regulators. But that this price...you can't blame them.

Has Potential Safety Issues
---------------------------As this is a kit for students and hobbyists, more care should have been taken to prevent accidental shorts from poor soldering. Including some small heat shrink tubing would remedy this situation

No Extra Parts
--------------
If you drop a nut, screw, or resistor...good luck. You'll have to get a new one. The only extra part in this kit is some slack in the wire you get.

.
.
.

While I wouldn't discourage anyone trying to get a great deal on a variable power supply, I would have to warn them that this kit will take a good deal of patience to assemble and you should buy heat shrink tubing for the ICs to avoid shorting them out. That being said, this is a great addition to a basic electronics lab if you don't have to assemble it yourself!
Poor packing led to broken PCB . This product was received with a broken PCB.It's pretty hard to break a PCB. Careless packing and handling are the only reason that this product could have shipped with a broken PCB. It would actually take effort to break the PCB so someone along the line must have known something wasn't right.I have to take this product down a notch since it is such a hassle to have to ship this back for a replacement. Who has time to take off work to stand in line at the post office to return things? Regardless of how well it may work when in good condition if the purchasing experience is unpleasant then reviews should reflect that. Had I known of this I'd have skipped it and paid more for a fully assembled unit. Whatever apparent savings there might have been from assembling it myself was lost when a defective item was shipped.....I'm bumping this up to two stars because having assembled it and gone through the instruction sheets I've actually decided it's a pretty cool old school design.However, the components are of pretty low quality and with the return issue I can't bring myself to take it up to three stars.
Elenco AC/DC triple output power supply kit . This kit is very good. It is easy to put together, and the final product is of high enough quality to use for years to come.I have read some complaints about soldering the binding posts. May I suggest that if you are having a problem in this area, that it is you who need to improve your technique. I had no problems soldering to these posts, and I am just getting back into electronics after many years away from it. You can do it easily, but only if your soldering technique is up to snuff.The only reason I am only giving this 4 stars is because of the rather lame method of attaching the transistors/voltage regulator ICs to the heatsink and then having to soldering wireds to each of their terminals. Come on Elenco, there are much better ways of doing this.Anyway, It took me a few hours to put together and it worked perfectly the first time out. Double check your work every step of the way, and you will be fine. Be especially vigilant when wiring the sections illustrated in Figure I on page 9. You don't want to miswire the AC.
Pretty Good . I don't have a lot of experience soldering so I started with a couple of Elenco soldering practice kits. By the time I finished those I was convinced my soldering skills were good enough to tackle this power supply kit.All in all it took me about 4 hours total and that included lots of breaks from actual work to carefully review the instructions.Like others have said, it would have been better if the IC's were mounted on the PCB versus the heat sink. I also had a quite a bit of trouble attaching wires to the binding posts but I got it done eventually. It helps that I have small hands. Anyone with big hands could have a bit more difficulty.Curiously, I got -1.25 to -16.6 V on the negative variable output and +1.25 to +17 V on the positive variable output. Not really sure why. All other tests checked out perfectly.As long as I don't go shaking this thing like crazy I feel that it will last for a long time.
Power supply . The power supply arrived on the advertised and neatly packaged. The instruction are very good. I was able to completely assemble and test the power supply in about 5 hours. I am slow, but steady and experienced with electronic kits. Two things stand out: 1) You need a decent soldering iron with a variable temperature control. The Sn based solder is MUCH more challenging to work with than the old Pb product. This has nothing to do with Elenco, lead is no longer used due to it's poisonous nature. I found that the solder traces, especially on the large 'lytic caps needed much more heat.2) Put a 2cm length of 5mm heat shrink tubing over the wire leading to base (middle) leads of the transistors and regulators mounted on the heat sink BEFORE soldering the leads. Again Sn based solder can lump easily, and there is not much room between the collector, base, or emitter. I also tinned both the wire and leads before I assembled this part of the kit.Other than these cautions I am enjoying my new power supply. It's nuthin' fancy, but I don't need anything really upscale. Remember, 1A is a lot of power when working or modern electronics.
AC/DC power supply . This power supply is an excellent value. It performs very well. The AC output is useful. I have kit building experience, so there was no problems in building this unit.

Cons Review
this could have been better . I've just finished assembling this. It works, but I find some of the assembly techniques cheap. The biggest one is highlighted in other reviews: the voltage regulators don't mount on a circuit board. They mount to a heat sink that sticks out the back of the unit. Wires are attached to the legs that go to the PCB. The instructions caution the assembler to be careful not to let the legs short together. Indeed. If only they had been mounted to a circuit board, there would be no danger.Other gripes: Some of the binding posts have to be tied together, rather than that just happening on the circuit board. The wiring is also pretty tight in there. The directions do a good job keeping everything accessible, but repair makes me nervous. I'm glad I didn't make any major mistakes!All the parts were included in my kit. My only problem parts-wise is that one of the PCB mounting legs snapped when I installed it. There isn't much extra included except a bit of wire.That all said, it is attractive, and the semiconductors seem fine and the circuits familiar and reasonable. The instructions are complete and reasonably well-written, and I expect no problems from this for a long time.

This review is from : TwinStar Silver 6" iOptron Computerized GPS Reflector Telescope
This is not a toy . This machine is amazing. Set up the tripod with the arrow pointing south and reasonably level. With the hand held, scan the planets. Select the moon. Hit enter. The telescope rotates to the moon or close to it. Look through the eyepiece and use the hand held to place the moon directly in the center of the eye piece. Then hit synchronize. It will stay on the moon all night. If you want to look at stars set it up on Venus. The resolution for accuracy is better on Venus than the moon because the moon is so big. Just amazing as it tracks the object you are looking at.

This review is from : Elenco Quad Power Solid-state DC Power Supply
Versatile good quality power supply on an economy budget. . I'm not one who is going to use a workbench power supply on a regular basis. However when I do need to test a circuit or power a kit then it's really handy to have one. In today's world of digital electronics the +/-5 and +/-12 volt levels are all you need. Add to that the higher amperages and you can do a lot with this supply. The analog displays aren't digital but they're clear and easy to read. That this Elenco supply isn't a kit is convenient but I think I'd have enjoyed building it. This unit is well made and a great value.

  • Made in the United States
  • Gain valuable experience working with printed circuit boards
  • Learn about multivibrator circuits
  • Build a fun two tone European siren




This review is from : Elenco Practical Soldering Project Kit
Practical Soldering Project Kit just right . I bought this as a gift for my 13 year old, to get him interested in electronics. The kit instructions are well written: they give practical advice, and two example circuits. The circuits, though simple, gave my son a sense of accomplishment when finish. This kit helps develop those skills needed for doing more advanced kits and projects. It's a great way, at a low cost/risk, to get the amateur hobbyist into electronics.
Elenco Practical Soldering Project Kit Reviews
Great intro to soldering . I needed some help assembling a few robotics boards so I enlisted the aid of my 15 year old son. He had never soldered before and this kit taught him the basics of printed circuit assembly. Immediately after he finished this "soldering course" he was helping me. Soldering is not hard at all, but it's great having something like this to teach the correct terminology and techniques.
Elenco Practical Soldering Project Kit Opinions
Great for teaching my kids to solder . My preteen twin boys love everything electrical. I wanted something simple that they could build that required some soldering. This kit was exactly what I wanted. Each boy built his own under my close supervision. They just loved building the kits. Next we will design and create our own circuit boards!
First toy that got me interested in Electrical Engineering . My parents were kind enough to buy this kit for me 15 years ago, and since then i've grown up and gotten an electrical engineering degree/career. It's a simple and wonderful way to introduce anyone to the basics of electronics - both in the activity of soldering, and in the high level understanding of resistors, capacitors, etc. A worthy investment in ones future.
Simple fun effective . I bought a couple of these to teach my ten-year old twins soldering skills and we had a ball. They learned to identify components, apply solder safely, test for unintended bridges, de-soldering, and basic electronic concepts. Perhaps the most fascinating aspect was reading color codes on resistors and then confirming their specs against a multimeter. There are enough exercises to develop a beginner's confidence with an iron quickly (although we used better rosin-core solder than comes with the kit), and one guy decided to omit the last step where you upgrade two resistors to modulate the circuit's oscillation: he liked the faster sound in contrast to his brother's board. All in all, these simple boards provided an inexpensive weekend of instructional fun.
Great way to learn to solder . I bought this for my 7yr-old so he could learn to solder and end up with something that would interest him. The device has two LEDs that flash alternately, and a siren that oscillates. It comes with everything you need but a soldering iron.The thing I loved about this was the practice pads on the back, and the very large, widely spaced pads throughout the board. With the practice pads, your kid can easily get the hang of what it means to solder and how it should go before they have to feel like they're starting on the project. Then, once they start on the project, there is plenty of space for them to build their confidence. The kit was put together well, easy to use and understand. For older kids with longer attention spans, the kit comes with a booklet with quite a bit of information, and a quiz. If you have a kid that is maybe 10-14, this would be for them.The one thing that bothered me about the kit was the lack of an on-off switch- so to stop the noise/lights you have to pull the battery, which annoyed my son as well. We'll add one on of course, but I think it would be the perfect addition to make the kit complete.
Simple and Cheap Way To learn Soldering . This is a simple kit that will introduce you to soldering while allowing you to avoid further breaking anything that you are trying to fix. Its is very easy to assemble the kit with the instructions provided and you will be able to do some simple soldering as I did when I removed my HVAC controller from my 1997 corvette and resoldered several loose tiny diodes that were not passing current and causing the display to gradually dim to where it could not be seen. It worked perfectly for a while but not so much anymore - but the point is that I was able to successfully solder them after first using this kit to figure it out. Go ahead and buy it and get your feet wet before you attempt to build a robot or something.
Exactly the same thing as Elenco Amerikit Learn to Solder Kit! . I ordered this kit along with the Elenco Amerikit Learn to Solder Kit to get some practice on a couple of projects before tackling some bigger projects involving LED Christmas lights. Come to find out, this is exactly the same product except that the Elenco Amerikit comes with a soldering iron and snippers. No where in the description of this item does it talk about building the siren and light and the description that is there is shady at best. Ironically enough, Amazon even suggests bundling the two items together with a solder sucker as a complete package. Why the heck would I need to do the same project twice? Misleading and frustrating. One kit is going back!
Great Practice . A lot of people have bought these for kids but it's great for adults too.I've been getting into electronics as a new wintertime hobby and I bought this just to practice soldering. The kit comes with detailed instructions that are easy to follow. The parts are very well labeled. The kit appears to be targeted to the classroom environment but I just did this in my garage. It took me a couple of hours to assemble and that included me taking lots of time to read and reread instructions. An experienced person could have probably done it in 30 minutes, but then again, why would an experience person bother? Unfortunately I could not get the siren working (I might have burned up the 555 I/C timer by applying too much heat). I did however get the alternating LED flash working. I also bought a slightly different Elenco soldering practice kit for additional learning.Practice makes perfect. I'm far from perfect but this kit has put me on the right path. For the price it's great practice. I'd rather screw this up than a real project with more expensive components.
Excellent kit! . I'm nearly 31 and used to solder all the time, got my HAM license when I was 15 and did a lot of my own radio repairs, however I hadn't soldered anything in 8 years or so and really hadn't touch resistors or any of these components in a long time. I saw this kit and thought it would be fun to get back into electronics and figured this was the perfect entrance back into that world. The kit has nearly everything you need. I found I needed a pair of needle nose pliers which the kit didn't include and a 9-volt battery to power the gizmo but the kit has everything else you need. soldering iron, solder, wire snips, Resistors, led's, etc. It took me around 30 minutes to put it all together. What I liked was this kit actually has a practice zone on the PC board so you can hone your solder skills on an actual board without fear of messing up. They have you make some brief solders, do a "repair" with a piece of wire, make a bridge and then clear the bridge. The kit really is very well done and the directions are clear, plus the board clearly lays out what goes where.When I thought I was done I connected a 9 volt battery and was expecting it all to work, the lights flashed but I couldn't get any sound out of it. After checking each solder connection I realized I left off a tiny little piece, once i soldered that last piece on and put the battery back on it worked perfectly.... and then I read where you had to de-solder and re-solder a different resister to "fix it" which is all part of the directions. The kit is excellent, I enjoyed it and will be picking up more of the Elenco project kits for soldering. It reminded me how much fun this stuff can be, and when you are done you have something to show for it. True the end gadget you make isn't that useful, but it's fun none the less, educational and worth the money.

This review is from : Magnetic Poetry - Shakespeare Edition
Thyne Magnets are Divine . This is a great set of words and most of the words you don't realize they're Shakespearean. There are some Old English like words of course and there are also some random words that they used during the Shakespearean time period, like "saucy" for example.
Magnetic Poetry - Shakespeare Edition Reviews
Very entertaining. . All of my friends love this, when they come over we always go and make shakespearean insults. This is a "must have" for all poets. All in all, a good buy.
Magnetic Poetry - Shakespeare Edition Opinions
certainly not a 'toy' . the review asked me to rate this 'toy.' I can't imagine any kid enjoying playing with Shakespeare magnets... it certainly is challenging! I've never read much Shakes, but it's fun to improve my vocab even in my 40's.

Feature Model A-R2 Kit Rock Tumbler

  • Heavy continuous duty, fan-cooled motor. Overload protected.
  • Uses two 3lb. capacity, long-life, molded rubber barrels
  • Versatile two-barrel, 6 lb. capacity tumbler




This review is from : Model A-R2 Kit Rock Tumbler
A great tool for an addicting hobby . First, I don't consider this a toy, but rather a tool for a hobby. A toy you play with. This, you put rocks in a barrel and leave it alone to do it's job.

But, it is a great tool. I got it for my girlfriend for Christmas. It caught me off guard when she said she wanted one, but I figured what the heck, why not. Now, almost 3 months after Christmas I'm finally writing a review. Why the delay? Because it takes a long time to finish the job.

Her first batch was with a bunch of various rocks we bought from another vendor. They looked just like a bunch of rocks, nothing fancy at all. Well, after about a week in the course grit, you could see these rock were going to look really nice. In time. All in all, the rocks went through various levels of grit, and finally polish, and came out with some very nice looking polished stones. The next step is to make some jewelry with some of the nicer ones. It's hard to believe the difference in what a plain looking rock looks like after several weeks of being ground down, smoothed and then polished.

Before her first batch was done, I decided I wanted to try some, too (a good reason to buy the two barrel model). I bought a couple pounds of Apache Tears. Well, after almost seven weeks, I took them out this past weekend. I found out after I started them, that Apache Tears are not easy to smooth and polish, but I'd already started them by then, so I was going to see it through. Wow, did they turn out great!

I do wish some of the instructions had been a bit clearer though. You need to oil the unit, but the instructions left me, at least, not sure exactly where and how to do so. Be careful when you oil it not to get any oil on the drums or rollers. The lids are a bit of a bear to get on and off until you figure it out, and perhaps there could have been better directions on those as well.

If you are going to get one of these, and you plan on doing two batches of rocks at a time, I would suggest you buy another drum, so you have at least three. Keep one for nothing but the polish stage, so you don't run the risk of contamination of the polish with some of the grit. A very thorough cleaning may alleviate that problem, but with the time it takes to complete a batch, the cost of a new barrel is negligible to ensure no problems. I actually bought two more barrels and use a different barrel for each stage. Mark them with a silver permanent marker (lids too) and you're good to go.

(Remember, too, this set is not a kit. You will need to buy the grit and polish separate.)

Although young kids will enjoy this, I still don't consider it a toy.
Model A-R2 Kit Rock Tumbler Reviews
This tumbler rocks . This is my first experience with a tumbler. The directions said to start with agates, (I didn't know what they were, so we went to a rock shop & bought some.) The tumbler works great, was made in the USA, and my 9 year old grandson is having a good time checking the progress every week. And so am I! It is incredible how beautiful the rocks are! This is more of a hobby tool than a toy, and I hope it will be something he will enjoy when he is older, too.
Model A-R2 Kit Rock Tumbler Opinions
Tumbler is Solid . Very good price, and quick shipping. I am using this tumbler to pre-finish my hand fabricated gold and silver jewelry. It saves me a ton of time on my clean-up and allows me to move on to my next piece while it is starting the process.
A-R2 rock tumbler . The tumbler is built like it will last forever. It's really not a toy.
Excellent for beginners and home hobbiest . I've never owned or used a rock tumbler so this was all new to me. I did not know that it takes as long as it did/does to tumble stones into a polished product; all phases of tumbling added it's between 3 and 4 weeks! But the unit ran non-stop overnight as the instructions say, you change the grit media (lil' messy but you get used to it & faster at it) at certain intervals and the end product is impressive. I think with some experience you could reduce the tumbling time. I did not use soft stones and again followed the instruction manual, I think with some actual gem stones and/or soft stones that would be the case that your tumbling time would be much shorter. But in the end it did really well. If anyone is making home jewelry/crafts or for a school project, this is ideal but again it may serve you best to begin the tumbling sometime prior to the start date of the actual project so they will be more ready. It's a quiet machine but the garage, laundry room or a separate crafts room would be better suited. Seems like its well made and should last a very long time.
Good Rock tumbler . Gave this rock tumbler to my sister for a Christmas gift. She's been tumbling rocks ever since! The rocks turned out so beautiful and shiny. She's very happy with it. And its not noisy!
Rock Tumbler . I am 59 years old and don't view this as a toy. I works great.
Dawn . This really isn't a toy but a product for a hobby. I bought it for my husband who enjoys turning rocks into smooth beautiful objects. It is well made and ordering from Amazon.com was easy.
Excellent hobbiest rock tumbler . I am now enjoying my first batch of tumbled and polished quartz beach stones. The results I obtained with this tumbler are highly satisfying. The stones have a high polish and I can see more beautiful depth and detail than when I plucked the wet stones from the surf.

I found the tumbler easy to use. I had one question about the tumbler and called the manufacturer and spoke to a very helpful and knowledgeable person who answered my questions (precisely where to oil the motor, how often, and which type of oil to use) who then went on to include several helpful hints for running the tumbler. As a result, I did not experience any malfunctions listed by any other reviewers (broken belt, leaking barrell), and my tumbled quartz stones are truly lovely.

I highly recommend this tumbler. In addition to revealing the beauty of polished stones to kids, it will also teach them patience and respect for a scientific/industrial process because they must perform specific steps to polish the stones and then wait for the final product. And when you think about that, it matches the fact that the original specimen, now laying shiny in their palm, took millions of years to form.

This tumbler is also made in America and that is something we can support with pride.
Nice seaglass tumbler! . Bought this to tumble broken glass into sea glass. Sturdy, quiet, does a nice job in a few days. Very happy with this tumbler. NOT cheap. This should last forever!

Excellent radio kit . The Elenco FM Radio Kit is an excellent product. The instructions are precise and easy to follow, and the parts are clearly identified. In addition, the testing guide, which tests your progress half way through and then at the end of the assembly is also excellent. This is the way a digital electric kit should be. It is top of the line!

Best Bug Out Game Reviews


Price : $9.99
BUY NOW
Bug Out Game Reviews - Bug Cards are scattered all over your table or even your living room floor! Players race to capture the bugs by covering each Bug Card with a matching Leaf Card. It is a wild scramble to find each bug! Be the first player to cover all of your matching Bug Cards and Bug Out!

Age Group: 5 and up. 2 to 6 Players.

Feature Bug Out Game

  • Manufacturer: Out of the Box Publishing
  • Age range: 12 and up / Number of players: 2 to 8 / Play time: 20 to 30 minutes




Soooo simple and fun! . My family has had a great time with this game. It's super simple. Just spread the round cards all over a big table (or the floor!) and give each person the same number of square cards. When you say "Go!" everyone frantically tries to match their square cards to the round ones. There's plenty of running into one another and squealing about not being able to find an image until on player plays the last card and yells "Bug Out!". Works great for all ages~~
Great for families . This is a great game that you can play to the level of the competition if playing with small children. They love finding the bug characters and covering them up. We play it on the floor with young kids and they loved it. Adults who are playing against one another can intensify the competition by playing faster.

A game that even preschoolers can learn and play, But Out is a great game. The cute bug characters make it even more enjoyable.
The more you spread the cards out the more fun it is! . Bug Out is great for the whole family, but especially fun for the younger kids! We like to spread the cards all over the living room floor so it almost becomes Twister like in the running, bumping-into-each other and laughing! Also a good game to use for very young children just learning matching (you will probably have to cut out the speed element if you go below 5).
Great Family Card Game . What a great game with innovative packaging. The bugs are adorable. Bug Out is a whole new level for matching games. The more area you can dedicate to the game; the better. What a great way to interact with your children and have fun at the same time!

good product good service a plus plus . it was cheap and it was easy to use and it had a lot of good instructions I like it a lot thank you

Cons Review
Flimsy doesn't include all needed tools . I bought this to teach a student to solder. I believe that more tools are needed to complete the project, including a pair of needle-nose pliers. Completing the project without them will burn one's fingers. Also, I believe that learning to use a solder sucker is necessary in learning soldering techniques. It may not be included because using one sometimes pulls up part of the printed circuit board. All in all, I don't recommend this product.
