great

I purchased this for my stainless steal RTIC tumbler and have a few issues. #1 the silicone seal absorbs the coffee color and is now permanently brown and #2 the seal isn't very tight and it leaks just a little bit.

The slide cover on my son's cup always slid closed while he was drinking. This lid is a great replacement for his faulty lid. They fit all of our cups with the same diameter opening, whether they are 30 oz or 40 oz.

During Covid we started drinking more water. Got a set of nice 30 ounce tumbles from Amazon and they were great drinking without the lids, but not so much with the stock lids. I drank with out lid and GF drank with straw.I saw these and thought they might fit our tumblers. and they did! She still uses the straw but I can drink with lid on. Which is great because if I knock over my cup, it will either only spill a little or not at all. The lid stays on secure and when the slide thing is open it will only spill a little when knocked over.Which has happened to me often at home and in my car.The quality of the clear plastic and the rubber gasket are better than my original one. Very easy to clean and dry.Price is much better than trying to buy the Yeti lid which we considered but it was expensive back then.

Most everything about this lid is great for my generic 20oz steel tumbler I got from work. It fits tight, the lid is indeed spillproof, and it's pretty easy to remove the seal around the lip.However, the main issue I have is that the sliding cover isn't easy to remove. When the cover is open, the ventilation hole vents directly under the slide, which makes it easy for steam and moisture to accumulate - prime mold environment. There's no clear way to remove the slide and properly clean the underside of it, I tried and ended up snapping one of the slide's guides. Luckily this is a two pack, but I won't be using the second one due to this cleaning issue.

These are great. The lids of my tumbler degraded over time, and these lids really renewed them. They fit fine and I have had no leaking.

Was about to give up on replacing the Broken lids on my cups. Then I found these!! Perfect replacements!! Good quality! Good price point! I am so happy!

They feel roughly as sturdy as the originals, but don't quite fit the same. I've got several 30oz tumblers made by multiple companies (Ozark Trail, Rtic, Yeti, Polar Camel, etc.). They fit a bit differently with each brand, as there is a small difference in the diameter of the openings (probably less than a millimeter between the largest and smallest). It fits decently in most, but it's most notably loose on the Ozark Trail model. It fits best on the Polar Camel. It can even leak some with an Ozark Trail, but really only seems to if you turn it completely upside down.As long as you don't expect it to be an exact replacement, you'll likely be happy with them.
