“Great little cap with a handle to carry! Note that the handle is just large enough to slide only one finger in. If you hand it to something using the clip then this should not be a problem. I had to suck a little too hardly to get the water flow going after tilting the bottle upwards.”
“I use the Waterdrop bottles for hydration when I go to the gym (among other places). At the gym, after touching all the shared equipment, I don't want to put my fingers on the part of the bottle I drink from. So I ordered the pull-up cap because I can pull the spout up with my teeth. It works well. I discovered that you have to pull carefully or else you can pull the pull-up part all the way out. I put it back in and it still works, but I ordered a second pull-up cap just in case. I also appreciate the loop for easy carrying.”
“This lid is difficult to drink from. The limited air flow means that you have to strain to drink from it, it makes a bunch of noise while drinking from it, and it leaks. Also, the rubber piece on the under side is a place for germs, bacteria, and built-up residue from the waterdrop tablets to accumulate. I don't think that it is a good design. It's difficult to keep clean. Not hygienic.”
