The bottle is great.
The cap, not so much. Wish I would have paid more attention to the other folks with cap problems. After only about a dozen uses, the plastic part of the cap detached from the steel screw part. So frustrating. Just like everyone else, it popped back in, but now it pops off every time I try to screw it in.
