I bought this for my 8 and 10 year old boys at the beginning of the pool season. We always blow through the plastic inflatables but didn't want to spend a huge amount of money for something from the pool store. This was perfect. My kids put this through the wringer, they would jump on it trying to surf, everyone would pile on it trying to sink it, and it withstood several beach adventures as well. A couple of times during heat waves we had to top off the air, but no leaks developed. The grommets seem like they may be starting to rust but I can't complain as we leave it outside exposed to the elements all the time. Overall, I am very happy with the purchase. It is really sturdy and it shows no sign of stopping, even with 100+ pund people jumping on it!
