“I wanted to love this cap. It is nice to have a finger handle type of option on the cap, and the pop up cap is such a good idea, but this is like sucking on a baby bottle. My husband can't stop laughing at the sounds it makes because air has to escape through the mouthpiece after each small swallow. You cant get a big drink without creating incredible pressure in your mouth. I can't use this in public. I bought 2 and regret it.”
“It's not bad, and really the only thing I've found that actually can get in and clean the glass bottles...but it doesn't clean the very bottom well nor the top where it curves so it's a struggle and I end up using the bottle more for plain water than with a drop, which sucks.”
