Query: So Bad

I ordered 3 of these for Burning Man. 1 of them already had a hole in it when I filled it halfway up for the first time. The other 2 filled up but within the first hour for BOTH, they started leaking. I didn't bring any of these in the end because every single one started leaking. Would not recommend this item for anybody for anything. Beware before purchasing. Not only did mine leak but I had several friends who purchased the exact same ones for Burning Man and more than 60% of them leaked.
