Bests & Worsts Reviews from Amazon

I loved these lids, especially since my RTIC tumbler's lid didn't have a cover for the mouth piece. The quality was as good as the original lid. The fit was perfect! The air-tightness of the lid was awesome as well which means no spills! On to the two minor quirks: 1) The lid wouldn't fit properly when I first attempted pressing it into the tumbler. Come to find out the seal is so good that if you don't have the plastic mouthpiece open when pressing the lid down the air pressure holds it up! Definitely an ok quirk once I realized why it was happening. Now I open the top when pressing down the lid. 2) Flipping the top back to drink works fairly well, however it's slightly awkward to drink from as portions of the top press against your nose.
