“The Bottle Brush works well, I hope WaterDrop will offer another one with a "J" shaped brush to reach the interior angle- at the neck of the bottle. That would be great. I gave it a 4 star because of that.”
“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.”
