Title: terrible flavor
Review: I don't know if it leaks or how much damage it can take. I've had it only a few hours and have decided my son will never drink from it. The rubber/silicone? valve is imparting a strong and disgusting flavor to the water even after several washings. Why go BPA free if something else is going to leech off into baby's drink??
