This bag seems sturdy enough, but it is awkward to use. I didn't send it back, because what you see is what you get, and the price was right. It serves it's purpose in that it holds/stores water, and is fine if you don't need to be getting into it more than once or twice a day. Of course, the selling point of a bag like this is that it collapses (in fact, it lays completely flat), when empty, otherwise, why would you buy this?
