“I bought this cap to replace the regular cap that was making shrill sounds when I twisted it open. Unfortunately, this pull-up cap is disappointing. Very little liquid flows out. I need quick, easy access to water during sports. Now, I twist the (quiet) pull-up cap off and drink directly from the bottle.”
“I ordered the pull-up cap to use with the insulated tumbler. It turns out it's only compatible with the glass bottle. I prefer using an insulated tumbler to keep the water cold, but I also like a pull-up lid compared to a wide opening. I struck out on both counts.”
