My children think this is the coolest thing ever. It works perfectly but the instructions it came with were confusing. I had to google how to assemble. I recommend, though! It’s really well made and I’m very happy with my purchase!

My only complaint is finding replacement parts. Ours has spent several years with growing boys, and is needing some TLC. If my search proves fruitless, I will buy a new one. It's that cool!

The most, best generator for the money. Pretty cool. The hand crank is nice, too... people are startled at how LITTLE they have to move the crank to get some real charge built up.By the way.... it comes with the discharge want. So don't be a moron and spend extra money buying one the way I did! :)

Our son sat for hours playing with this just the reaction I was hoping for out of a 29 year old. He is a real child geek at heart. Made his Christmas a blast. Will absolutely buy from this seller again.
