This is a pretty decent lid, it doesn't leak and fits my cup perfectly. The only complaint I have is the placement of the air release hole. I don't know the technical term, but it's the hole that allows the liquid to flow out of the drink hole. The air hole on this lid is right by the drink hole so you get this weird gurgling, bubbling and basically have to suck the drink out like a caprisun. My fix? I create my own hole with a knife toward the back of the lid.
