“I purchased 4 of these for the cups my family ordered. On the whole, these work as advertised. They do like to pop out of the 16oz Pints but in my experience that went away after putting a few cups of coffee through it. My wife's didn't work nearly as well as mine though. I did write the company and ask them about the issue, they replied promptly and with helpful information. They also sent us a sample of the new version of the lid. Now THAT version worked flawlessly right off the bat. It has a different method of adhering to the side walls of the cup that really does make a difference. I would also like to say the originals worked on my kids 12oz and 8oz cups perfectly. So other than the minor and temporary inconvenience of the popping issue, all of the lids have worked very well since day one.”
“I bought this for my husband. He liked the feel of the lid. His only complaint was that when you grab the cup because it does give a little, it causes the lid to raise up often. He said he is constantly having to push it back down. Aside from that he likes it.”
“Very impressed with the lids so far. I was skeptical that they wouldn't leak/drip.... but they don't! The rubber feeling on your mouth/teeth takes some getting used to.”
