My 10 year old son LOVED this bag! Unfortunately it only lasted two months because he played with it so much and so hard that it kept getting slow leaks of air. We finally had to throw it out. My son is so sad and wants another one, but I can't afford another right now.
Bag is cheep, you fill it with water at the bottom but it still doesn't stay up. Kids kept having to put it up against the wall or chair.
Finally I just bought another from toys r us and got rid of this one for good. Only thing I kept on it was the talking punching part that you put around the bag. I wouldnt recommend this to anyone
