Title: Chirps like a bird
Review: I got this bottle with the sport cap. It's really nice in concept, but there are some problems with it. First of all, the sport cap chirps loudly like a bird when you drink from it, which is rather embarassing. Secondly, I, too, find that it imparts a strong metallic taste to the water. I haven't given up on it -- maybe I will try switching to another type of cap and see if there's some way I can clean it to improve the taste. I really support the effort to make a safe water bottle, and I hope Klean Kanteen will work on fixing the problems.
