I bought these for my kids 6 and 3 for Christmas. They really enjoyed playing with it until they speared it. I don't blame the product for the puncture, I think my kids damaged it with a stick. However, the punching bag part did not inflate easily and did not hold the air for long. Had to inflate every few hours. Even a fully inflated punching bag would not stand upright. The kids loved playing with it for a while but I wouldn't buy it again.
