Review on Sports Bottle Leakproof Eco Friendly Outdoors by Paul Wall

Stopped working after a few uses. Suck on a straw, but no water. I had to unscrew the lid a bit to make it work. It appeared to be an air problem, but the hole in the lid was clean. The bottle worked after I pulled a little on the drinking part on the top cap and straw underneath. Has been working ever since. Otherwise I like the 18oz bottle. It's great that the drinking area is covered when not in use. keeps clean.
