Review on Inflatable Bounce Jumping: Doctor Dolphin Delivers Endless Fun! by Bryan Cavalcante

There is nothing better than this product. It was larger and less expensive than other alternatives I researched. Great for our 3 year old in our basement. Not too big for interior space and fast up and down. My older 6 and 10 year old nieces also used it. They were rougher on it, so if it were a primary user I'd be more comfortable tying it to the ground outside. Inside without a strap for small children ok. I don't think my nieces were too big for that.
