DOCIK Leak Proof Slider Lid for YETI 20 Oz Tumbler 10 Oz Lowball and 10 oz Stackable Mug, Spill Proof Splash Resistant Lid Cover Also for 20 Oz Ozark Trail Insulated Coffee Travel Tumbler Cup, 1 Pack

The slide closure on my Yeti 20 oz mug would not stay put so I ordered this as a replacement. Although it is the same "size", it is a slight bit smaller and the lid easily lifts off. It does not stay snug in the mug. I even replaced the gasket, but not an improvement.Fortunately, my nose rests on the lid as I drink and I'm focused on watching for leaks. Note to the design team - double-check your size and enhance it slightly.

These are great replacement lids. I am so thrilled to find these. They seem the same quality as the original lid I needed to replace. Love them!

Fits my cup perfectly, I measured my cup before I ordered! They only thing I dont care for is when it gets tipped over the air the slider fills up with fluid. Other than that this product is worth the buy and functions well.

This lid is perfect. When my Yeti fell 2 times in 1 week and both lids shattered I was devastated, assuming the lid would be a $15 spend. These work great, 2 for $6! My only reason for the 4 stars is that it doesn't flow that well when you need a quick gulp of whatever beverage you have in it.I haven't filled it and tried to make it leak though I'm sure it could if you made the right mistakes an forced it somehow. I've had it unknowingly tip on its side in my work bag for at least 10 minutes without leaking a drop!It fits perfectly and works as it should. So far, so good 👍 and I'll loop around later in life to comment on it longevity.

It’s a decent product for being an aftermarket product. If the sealing quality was better as far as the lid to the cup, then it would get five stars. I can see this possibly losing it’s sealing ability. I just hope that it lasts more then a few months (because the price is good for what it does).

Not too happy with these and will probably not purchase again.

The lids do not fit the cups they claim to fit. I have those specific cups and these lids do not fit the 20 oz cups, they are too small

I'm disappointed with these lids! They are hard to drink out of because of the lip design. I've burned my tongue & lips because the hot liquid doesn't flow consistently. They are also hard to clean. You can not take them apart to clean inside the slider, even after soaking them in hot, soapy water. The gasket comes off when you try to remove the lid too. I will not order again.
