“There is no air hole in this top so you cannot drink out of it like a normal water bottle. You have to essentially pour the water into your mouth. Very annoying”
“Sorry, I love these water bottles--quality, design, etc.,--but fully expected this lid to be ventilated so could use it when exercising. As it is, you just have to pour water into your mouth. I like that the dispensing area is covered by a cap (for sanitary reasons), but just cannot live with the way the water is dispensed. Had to return.”
