In my opinion, it's better than nothing but not by much. There are weak points where the plastic is clearly thinner than in other areas, the spigot doesn't flow much and it's a pain to fill by yourself. Picture filling a 5 gallon garbage bag with water through an offset 2 inch opening with one hand and that's a pretty good description of how it works. Similarly, it sits on whatever surface you intend to put it on like a water-filled garbage bag. Honestly, if you're looking for something like this, spend a few extra dollars and get one that has a rigid body rather than this flaccid sack of aggravation.
