Anyone use them and are they a good choice? It can fit in my temp control fridge were a conical would not. I'm thinking of getting one because a batch of beers I've made taste like plastic. Still puzzled as to why but fear that my plastic fermenters have done too many miles perhaps. Plastic stains and retains smell etc. I feel that stainless or glass is really the only true cure of this but I don't want to use glass carboys.
