This is bull****! Just had to toss another Better Bottle. Second one this month and third one this year. They were my oldest. Probably 3-4 years old. They all developed a small crack and very slowly leaked (thank God). I did notice the bottoms were a bit soft. I've got a couple 5 gallon BB's that are newer and I can tell the difference between those and the ones that crapped out. I have heard they don't like PBW and I now believe it. I also use Oxyclean. Have not heard if this is also bad. I do soak over night. Once in a blue moon it might soak for 2 days. I'm not buying anymore. I'll stick to stainless, pails and Spiedel fermenters from now on!!!
