Bought this several years ago and dumped a dirty water out couple days later and never filled it again. It takes a lot of water and since there is no filtering system, you have to empty and refill quite a lot. I put it in a garage, even bumped into it with my car couple times, then finally put it away deflated. Finally got it out again for my now two year old and the pool is still fine, it withstood all the abuse. If you don't mind emptying and refilling frequently even with a little bit of bleach, this pool will serve you well. To empty is a pain though as the plug is on the bottom and if you don't lift it up somehow, the water just sits there. Inflating it takes a while with a camping pump, can't do this by mouth.
