Review: 

This kit is one of a number of kits aimed at giving children hands on experiments with electronics. It includes a battery holder, 2 capacitors, 2 resistors, 1 pot, 2 bipolar transistors, 2 leds, speaker, mike, motor, a variety of switches, 4 "IC's" and a few other parts.

The unit and connector mechanism is the thing that sets this kit apart from most other kits. The schematic symbol is the predominant feature of most of the elements. This makes the experiment itself look like a schematic diagram. Since I am an electrical engineer this is what convinced me to buy this kit (a little more expensive than it's Radio Shack counterparts). The schematic symbols are usually meaningful icons of what the electronics REALLY are and do.
However, while the idea is fetching the implementation is lacking. Immediately out of the box some connections were hard to make and prone to intermittancy. Simply put, the first circuit we put together did not work until we substituted some parts!! The connectors are like a specialized snap. But the connections aren't always sound; and this can cause an experiment to fail through no fault of the student. This is a fatal flaw. For this reason I don't recommend this kit.
The documentation comes in two parts. One is just pictures of the circuits (schematics but with keyed colors so they are easier to read for little ones). The other offers explanations. The explanations for this kit are very average. Lastly, it seems that most kits fall short when it comes to their "IC's". This, like most kits, treats them as black boxes with no insight into what is happening within them. It is more like magic than science when building circuits with them.

Note: The product is made in China
