Meets expectations
We received these lid rings on time and packaged as new product. No signs of previous wear & tear. They fit both our Yeti 20 and 10 ounce mugs. They also fit my Ozark mountain 20 ounce stainless steel mug. The fit is not exactly as tight or as thick as the original Yeti mugs, but it does secure the lid and there are no "splash incidents" which came out of the cup lid seal. I cannot really attest to durability at this time, because I have only used and washed them once. I did notice that after the ring is removed, washed, allowed to dry, then place back on the lid, they seals appeared to me to expand and provide even a tighter fit. Because of this, I am giving it 5 stars. Fast shipping, good packaging, and proper fit meets and exceeds my expectations. Received an email from seller upon shipment and immediately after shipment arrived to see if it got there on time. No complaints at all from me. I will probably buy from this seller again if they have products that I have a need for.

Nice replacement gasket.
These gasket work well and allow me to clean the gasket while still using my tumbler. Not quite as thick as I hoped. Yeti lid closes but isn’t quite as tight as I’d like. No leaks but looser fitting.

Doesn't work with my 20oz Yeti mug even though they claim it does
I bought this to replace the gasket on the top of my 20 oz Yeti thermal coffee mug. They claimed it would fit - It DOES fit on the lid, but doesn't make contact with the mug so no seal is ever formed and trying to use would result in hot coffee pouring out from around this useless grommet and scalding the drinker. This grommet was completely useless and a total waste of time and money - if you're looking for a reliable replacement for a Yeti product, I can't speak, to others, but for my 20 oz mug, this was useless.FOLLOW UP: Based on my review, I was contacted by a customer service representative for the company who kindly offered a refund or a replacement. I accepted their offer for the refund. This didn't work for me, but fortunately, the company is a concerned seller that you get what you paid for, and if the product didn't meet expectations or didn't work,they refunded my purchase without any further action required on my part. It's good to know that this is a company that stands behind their products and are concerned about a customer's satisfaction.

Work great
Used it on an uncommon Life Is Good tumbler and it fit perfectly. Thought I was going to retire it but not anymore.

work great
well, I have the Primula Avalanche cups. I needed these for my 20oz ones. They work perfect. I just really needed one, but its nice to have extra's. It was a tad tight at first, but I took the lid off and on several times and it seems to work better now. I'm sure after I take the lid off some more it will be perfect. it was the correct size. I looked at a lot of them. This seemed to be the closest to how my original ones are made. so I am happy.
