“I like the cap but it is a little hard to get the cap closed, and I have a hard time with the seal. I either can't get enough water to come out or it feels like I'm drinking carbonated water because it's coming out so aerated and fast. When it is working, though, I love it. I love not having to unscrew the top to get a drink.”
“Ugh ~ not sure why these pull-up caps just do not work for me. I tried taking the plastic do-dad out and then when I turn my bottle 'upside down' to mix the water around inside, water comes out of the top vent hole. Still more convenient than having to screw & unscrew a regular cap, so I will deal with it”
