Familiarity: I've put it through the wringer
I really do enjoy this lid! It's great, but be careful putting hot liquid in it and then immediately closing and "shaking" the bottle, you will hear the air seep out because of pressure and that could cause some liquid to seep out. It also reduces the ability to keep the liquid hit for as long as the other style lids but other than that I love it! I even use it to carry liquid and I pour liquid into a little cup and it pours really well! Good lid.
