dscvr2 Pcs Tumbler Replacement Lid Spill Proof, Shatter Resistant, Perfect Fit Lids Compatible with YETI Rambler, Ozark Trails,Fits Inside Diameter of 3.75 inch Tumbler (30 oz., Black)

Works as advertised. Lid closes and opens easily, stays put when closed or opened and doesn't leak.

Fits very good and I really like the lid top. It flips over for a good tight seal and makes it easy to clean.

These work great on my 20 oz Yeti cups! I can shake up my liquid and nothing spills! I have not dropped it or turned it over to see if it leaks. I am very happy with them so far!

Fits well and has a good seal. Doesn’t need to be as wide

These kids are some of the better lids that I have bought and I have bought many. These are comfortable to drink from (which was not why I bought them). They fit my glasses very well! I will definitely be buying more of them.

Works for Hubby's Beast 20oz tumbler but when hot drinks are used you need to pop the drink top to let the steam escape or the lid will pop up slightly with the chance of leakage. Is good quality and easier to clean than the original cap.

I got these for a few cups cause our others had broken.They fit perfectly, easy to clean and remove

These are the best lids I've found overall, and way better than any stock lid from yeti or ozark. But yes, they do have a quirk...One of the most common complaints is that the seal will pop when hot. I had this happen once and then figure out how to handle it.Basic thermal physics, folks.When you pour your hot drink in it, put the lid on, flip the black plastic lid to the close position, but do NOT push it down to seal it right away. Let it sit for a minute and THEN push it down to seal it.Works perfectly.Mine eventually wore out after a few years resulting in a little bit of my coffee getting beyond the seals on bumpy rides, but they've been great... so I'm buying them again.

These were great! They were well made. I love how the lid clipped to the other side of the rim when you sipped because it didn’t hit my nose. They are very durable. I dropped my cup on the hardwood floor and nothing happened. The lid didn’t even pop off.

Wow! I've just received my new tumbler lids from these guys and they are awesome! Head and shoulders above the competition.The fit is perfect and the design feels incredibly secure and does not interfere with your nose when drinking.100% recommended

Working great so far. Doesn't leak as long as you wait for a minute to close the lid after pouring in your hot beverage. Doesn't touch the nose either when you tilt the cup to drink since it locks all the way to the other (open) end.

This tumbler lid is virtually leak proof which we need for taking out on the motorcycle. The Yeti lid splashed our beverage out constantly and this one doesn’t at all. It’s important to release the steam pressure before sealing the flip down so the pressure doesn’t push the lid off. Our coffee/tea stays hot for a few hours, which is nice. The quality of the lid seems solid. I’m so glad we got these as replacements.

As other users have mentioned, it's 100% leak proof, but this comes at a price. Steam has no way to escape and will pop the lid off of the rambler, then coffee will spill everywhere. You either need to let steam escape periodically, or make sure you only fill the rambler half way. I've managed to learn how to use this properly, but it's a bit of a learning curve.
