I've been using this whenever we camp, for the last two years. I would have given it 5 stars but the stream of the water flow was a huge downer for me. Call me impatient, but I don't enjoy standing there as long as I had to, just to fill a 16 oz. glass of water. So we basically just use this to wash our hands/face and brushing our teeth. We haven't had any problem with it rolling around or the flimsiness about it, but that's because we always hang it from a tree for easy access, and never used it on a table. It's probably flimsy so it can collapse for easy storage. I'm about to order a new one, and if the water flow wasn't so slow, I would have purchased this one again. But I'm trying a different one that looks like it has better flow.
