Fun way intro to electronics . -Overall a good product, I just need to complain about the headset that came with it, I had to replace with another set to make it work.
This review is from : Crystal Radio Experiment Kit,
It actually works...with speakers . Well I got this for a school project, it took about 30 mins to build. It comes with step by step instructions which are very straight forward for the most part. The challenge came with actually trying to get sound out of it.
The little speaker that comes with it is not loud enough for you to hear anything. When my teacher connected it to speakers ( he did with all the other students) it was reeaallly clear and loud! I mean I was very surprised, we actually got like three stations; no static, very clear! I was pleasantly surprised.Pros: -Cheap although as I am writing this it is significantly cheaper than when I bought it :(
-Easy to put together
-Fun once you actually get sound out of it.Cons: - Like I mentioned you probably will need speakers to actually be able to hear anything.
-It really is just the blue frame, with really long wires and plastic parts, I think there is more challenging crystal radio's to build on amazon if that's what you are looking for.Generally I like it.

Crystal Radio Experiment Kit, Reviews
Easy to assemble. . Please do not be impressed by the fact that I have scratch built numerous crystal radios. This radio is one of the easiest to assemble. The most difficult part of building a crystal radio is making the antennae. Make certain that you have a good ground and a long antennae. I would recommend at least at 50 foot long wire for the antennae. If your antennae and ground is good, your reception will equal any car radio. In fact, your primary problem will be that many of the stations are so loud that your ears will hurt.

Crystal Radio Experiment Kit, Opinions
Science fun . My 9 year old daughter and her dad put this together. They had a great time together while they did it. The spent some good time together and she learned alot about how radios work. It is a simple kit, very easy to do.

Crystal Radio . I bought this for my 8 year old as a Cub Scout project. While it's pretty simple and straight forward, the spring connectors are pretty touchy for a child's fingers (for an adults fingers, too).
So far, all we have is hum (hummmmmmmmmmmmmmmm), but we're going to a)try for a better ground, and b)take the radio physically closer to an AM station. The good news is that all he needs to do is build it to satisfy the Cub Scout requirements. Check!
I know it should work, so we're going to persevere.

Educational . This toy is fun to put together, and fun to use. I enjoy using this radio, because from the very beginning it caught my attention. I recommended for parents to buy and kids to use.
Disappointed . I purchased this for my cub scout den. The boys had a great time putting it together and learning. However, it didn't work. We tried our best to tune into Tokyo with no luck.
Cons Review
Good in principle poor in execution . My son needed to build a crystal diode radio for the Communications Merit Badge in the Boy Scouts. I searched the internet to find a good price and this was it. The instructions were fairly easy to understand and my son built it himself without supervision. But he was unable to get it working. I took a look at it and found that the problems he had were primarily due to incorrectly orienting the kit's chassis to the drawing. Maybe colored springs would make it easier to know what connects where but I can't fault them for that, there needs to be some challenge. The real issue I have with the radio is it doesn't pull in radio stations very well.
From my own experimentation I grounded the kit correctly and hung the antenna at its full height. I could only find one radio station and it was so quiet I could just hear the peaks of the conversation. I went over the connection two more times to ensure that I hadn't shorted anything (a real problem with spring clips) and never achieved any better reception. However the radio worked just enough for my son to get his merit badge.
I have built these radios when I was a kid and they actually worked well. I think this needs to be re-engineered to improve the sensitivity and increase the volume coming out of the ear phone.

It really works . But not wonderfully well. And then what do you do? It's a one afternoon toy. Then it sits in the corner and collects dust. It's not good enough to really listen in. I wish the old Heath kits were still around. I hear they no longer exist. At least with that you got something worthwhile.
