Kids Circuit Board Building Kit

This looks like exactly what it is - an Elenco knock-off. The quality of the circuit components themselves is comparable to Elenco's product, so they can be used interchangeably, and there's a touch-sensor that isn't in the Elenco base model set, but the instruction booklet is just a black & white sheet of paper. When it comes to engaging kids and ease of assembly, the instructions matter, and Elenco is better hands-down. Elenco's packaging is nicer, too, if you're giving as a gift.
