"I looked at lots of reviews of other water bottles and they all leaked according to the reviews I read. When I first got these I put water in them and guess what....
yep, they leaked. BUT, I took the little black "O" ring out of the lid that was in the cap that came on the bottle and added it inside of the lid on the drinking portion and NO
MORE LEAKS! I've had these on my dog crates for over a week and still no leaks. They're a little harder to fit on some crates than others...the spring that attaches to the front of the crate is extremely strong, but once you get it on it isn't going anywhwere."
