“I like the cap concept, and it has a great mouthfeel, but unfortunately, the flow of water is too limited and slow and requires too much suction to draw it out. My face hurts after using it all day! Plus, while drinking, the cap makes strange and loud noises.”
“The cap works great. Saves time, not having to unscrew the top. Helps to keep it from spilling. I do miss the look of the original, screw-off cap. That cap is beautiful.”
