DOOPOOTOO Drinkware Spill and Splash Resistant Tumbler Lid for Yeti Rambler and RTIC Tumblers For 20 Ounce Tumbler 2 Pack

These weren't a great fit for my RTIC 20 oz tumblers. The fit problem appears to be the rubber gasket. Although not as tall as the original, these gaskets are larger in outside diameter and are very difficult to push in or pop out and don't go down flush. After swapping an original RTIC gasket the top fit fine. There also seems to be some quality control issues as well. One of the two I received had what appeared to be a crack in side the rim under the gasket which seemed to be inside the plastic and had bead of plastic at the end of the crack that I had to scrape so the gasket was flush to the rim. If I had to use these with the supplied gaskets, they would never be used. That said the one without defects works just fine as long as I use the RTIC gasket.

The fit in my 20 oz tumbler is fabulous. The only wonky thing about these lids are how loose the sliding flap is. Sometimes it can be a bit of a challenge to keep the flapper from falling when taking a drink.Edit: After using the lids for a year now, I have thrown them away as it is too irritating to fight the flap when trying to take a drink.

They don't close all the way. They do stop liquid from spilling out of my 20 Yeti, but the tops don't fit completely into the tumbler as the tops don't go all the way down. If it wasn't for this, I'd give them 5 stars. Yeah, the tops come out a bit of the cup, not good for a "Spill and Splash resistant" top.

Very Please with this purchase. However, the lid is not "SPILL" proof. it does still leak (which was expected in my eyes) however, it will definitely keep from major spillage all over the place! i bought this for my 20oz Yeti and it works like a charm. I gave the other one to my mother who had an Ozark Trail 20oz from walmart and it also fit great!

good plastic but the lid slider doesn't stay or lock in place so that it stays open or closed. It needs a detent built in for slide locking. However it does fit tightly to the cup and keeps your drink from splashing out the top accidentally. It will leak if you tip the cup over as it is not leakproof, only spill and splash resistant. For the price I got what I ordered. I forgot to add, after further inspection, that the slider does pop out very easily for cleaning under the slide also.

These tops to 20oz RTIC tumblers are the same as those that are sold by the name brand. The prices for replacements (they break if dropped) was crazy. I got one for $5 and then they were $15 when I needed another one. Two of these were less than $5.

We bought this 2-pack and they worked great at first but after 2 months, the slide on one of the lids had a clip break clean off making it useless. The slide lid was only removed to clean the lid. The other lid is still working but I don't think it will last long either.

Fits RTOC cup well. Slider doesn't align properly with air pinhole. Became loose quickly. Would stick with known brand for next purchase.

works well
