This item worked for 5 minutes and then the lights stopped working. The thunder kept working but no lightning, so sent it back and they sent another. The same thing happened again!!! So I called thinking we might be doing something wrong but we were not. They sent another one, it worked for a few minutes and then the lightning stopped again. obviously there is some type of "short" in the item. It would be a neat toy to watch and learn with but without the lightning it just doesn't work. I think we gave it a fair try also, 3 times. The company was good about returns and sending another but they need to fix the problem.
