Madd Gear Booster Blue

Strap broke first day of use. Not very springy at all. I gave two starts (instead of one) because three days after receiving kids are still enjoying stomping around in them and still seem pretty excited (I think they like being taller). However, they are not doing what they were bought to do.

On the box, it shows a kid jumping, you cannot jump in these, there is no give in them whatsoever. Nothing lights up, just gives them about 4 inches in height, does nothing else. Wish I would of pulled them out of the box when I bought them, what a waste of money, Don't buy them
