Great, besides the leaking (i figured out how to..
I too had the leaking problem. But i finally figured out how to avoid it. You gotta watch and/or feel how tight you tighten it. TOO tight, it leaks. Too loose, it leaks. So you have to feel for it. Right when it closes, then allow it to close just a tiny bit more. Practice practice practice. if it leaks, try again, but remove the top, wipe away the rim of the bottle, and the inside of the top part. These are the best bottles, but i too dislike how much they leak. Again, i finally figured out go to stop the leaking. Hope that helps.
