“Wow! Bought this as a Christmas gift for my 9 year old son who wants to be an inventor....he has been in the next room building and learning about circuits in series, Hz, and amperage for the past 3 hours, the morning after Christmas. My husband, who trained as an electrician in the Navy, is so impressed with the instructional and hands on approach, he says that the Navy needs these to train on! Would give this 10 stars!!!”
