TumTum 2 NEW Spill Proof Yeti Lids & Rtic Lids Tumbler 30 oz - No Leak & Splash Resistant Premium Quality - BPA Free Vacuum Black Locking Open Close - Straw Friendly, Fitted Ozark Rambler

This lid does a great job at preventing spills and leaks, but has some drawbacks. The lid has a very tight fit on my Rtic 30oz. This is a good thing when it comes to preventing leaks, but is ridiculously hard to remove. The stopper is also poorly designed and hits your nose when you try to take a drink. The air hole is also too low and when the cup is more than halfway full you can barely tip it before your beverage is blocking the air hole.

I really like these waterproof lids. I use them on my Arctic mug while walking the golf course. Beware that they don't do well with soda in the container because these lids make it airtight and the jostled soda causes gas build up that will pop the lid off. No spills with water, so that the way I roll.

Don't waste your money on this it's not worth the price and the closer tabs will break very easily. Extremely difficult to open even for a grown man with strong hands!!!!

I wouldn't recommend these lids. The lid stays on very tight, and its basically spill proof. BUT, you can hardly drink out of it. The lid doesn't fold back all the way and it hits your nose every sip. You cannot take a full sip out of it. Not a great design at all.

This lid is better than what came with the original Rtic. It is perfect and the quality is fantastic.

Arrived as advertised - fit great!

You'd think that spending all that money on an authentic Yeti they'd toss in the spill proof lid... LOL.

I purchased this for my 20 oz. RTIC tumbler and the fit was perfect and no leaks when inverted. The only problem I have with it, is that my average size nose touches the locking hinge and makes it difficult to drink from. If you drink with a straw, I am sure this would be a perfect spill proof lid.
