The ideal kit for practicing your soldering skills. Most practice kits available only handle the soldering part, solder a few resistors and LEDs that is it, you never know if it was done right. This practice kit is a working circuit. After soldering you can power it up and see if it works, every resistor, cap, LED, and chip has a function. If there is something that does not work you can quickly follow the trace and fix the problem and test again.
