Material seems thicker and higher quality. Snug, truly airtight seal.

These fit perfectly on 20oz yeti, polar camel, and harbor freight tumblers. Second set of replacement lids that i've purchased, because the last set was a total bust.

"would purchase again without hesitation" "small instruction tag containing thoughtful, helpful, clear description and explanations" "no complaints.

Lid fits so much better over the oem lid, which was scary loose fitting. This lid feels like it would hold strong if it were knocked over and would keep from spilling or leaking the contents.

The lid leaks around the rim more than the original yeti lid. The lid itself is almost 3 1/2 and is too big for the cups i'm looking for.

Pressure from a hot beverage lifts the lid right off the mug. The it's difficult to get a good gulp from this lid.
