Tumbler Lid for 20 Oz Yeti, Rtic Rambler and 10 oz Lowball Tumblers - Leak, Splash Proof Proof and Straw Friendly (Lid Only) (Black)

Works great, drinking a cup of coffee with this on it right now, I can turn it upsidedown and no coffee leaks out when closed. Its such an airtight seal that when you close the top it will actually push up a bit on the lid, showing its not even letting air escape. Its also a recessed sipping hole which is nice because it allows a a good slurp of coffee to get the right flavor and cool it a bit before it hits your tongue, very well designed lid.

It's great for sealing your cup, but impossible to drink out of- The lid flips up in such a way that prevents human mouths from reaching the cup.

What i like the most about this lid it has a tight secured fit unlike other lid's i have purchased in the past the pop up seems to much better than the ones that slide open that seems to get loosen over a short time,if it open just a little further it would be awesome only time will tell if it will hold up

THE BEST!! It fits perfectly on my YETTI to create a spill proof seal. It is also easy to clean. The only minor flaw is that the lid sometimes pop up a little if the contents are TOO hot. It’s a very easy fix though. I don’t use any other lid for my yeti!

Great lid. Won't leak, but is not the kind to hold upside down as the lid doesn't screw on (not intended to work that way). It is great at being splashproof or possibly if accidentally tipped over.

Works ok. Definitely stops liquid from leaking. It has some problems though. First, it works a little too good in terms of stopping it from leaking. It does not have any sort of vent, so several times already the pressure from the steam will build up and pop the lid right off. Second, once you get down to the end of your drink, you cant really tilt it back very far because the little flap hits your nose and wets it. Overall its ok, but I will probably buy another one and hope it works better.

The first time I used it, I turned it sideways to see if it leaks. The lid was on properly but the pressure created by the hot coffee expelled the lid and coffee sprayed all over. It also did not keep my coffee hot any longer than the stock lid with a hole in it that came with my Yeti tumbler.

Works just like the 30 oz version. 100% leak-proof. Lid is a good tight fit. Tip: crack open the hole-cover before trying to pry off the lid.

It keeps dirt and what not out but it doesn't 'stay sealed' (the lid itself rises up a bit)
