Compatible with YETI Rambler, Ozark Trail, Old Style Rtic, and More - Magnetic Slider Switch Spill Proof Tumbler Cover (Black 30oz 2Pcs)

First off, I will say that this definitely isn't leak- or spill-proof. It's certainly more leak-proof than no cover at all, but liquid does get around the magnetic cover so care is still required not to tip the tumbler too much. A bit disappointing since I wanted something totally spill-proof that would fit the Yeti, but I like them enough otherwise to use them. They fit my 20 oz Yeti perfectly, and the seal around the lip of the cup is very secure. The magnetic piece is removed easily enough for cleaning (but it also doesn't pop off without warning; the magnet is pretty secure). So far it seems pretty well made, as well. I've dropped one a couple times and haven't had any cracks appear, so at least my butterfingers aren't a threat to the lids. As long as you aren't looking for a lid that will completely stop spillage, these are a good way to go, and its a good price for 2 lids. EDIT 6/6/23 These lids continue to survive my clumsiness. And for the 3rd time since I got them have saved my laptop from that clumsiness as well. I learn for a little while after each incident not to leave my cup where I can knock it over but I always slack off again eventually. This morning was one of those times. I turned away from my cup and laptop to tend to something, turned back around...and knocked my Yeti over. Again. Right onto my laptop. I was able to grab the cup before it had a chance to leak but the fact that the magnetic lid was in place, and stayed in place, saved me from having to send my laptop in for repairs. It didn't spill. A few drops of coffee did splatter, but nothing damaging. So yeah, it's definitely not leak proof but it's getting 5 stars now because even after all this time the magnet is still strong enough to keep it in place when it gets knocked over. And that was enough to save my laptop.

This was a perfect fit for my cup and I love the magnet stopper! Still very happy with this purchase a couple years later!

We don’t own any other Yeti products, except for this single lid, and it’s been a great addition! It works much better than the original lid that came with our cup, providing a tighter seal and preventing spills. What’s even better is that it fits perfectly onto other brands as well, making it a versatile option. Overall, we’re really impressed with the quality and functionality of this lid!

This was the second purchase of this item. One lid was black, the other was supposed to be navy. The first time, I thought the color was an error. It’s a navy blue was really a dark teal color. It happened to match a cup I had, so I kept it. I ordered a second time to get the navy blue for another tumbler I have. Nope. Still received dark teal. I’m disappointed, but like the lid and will keep it. Not sure I like the pointed magnet slider, but it functions fine. I do like the pointed piece on the lid. It makes removal easier. The lid fits all the different brands of 20 oz tumblers we own.

These fit a 20oz Tervis perfectly! I don’t think it was one of the brands listed in the description that would fit, so I thought I would give them a shot. Some say they leak if your cup is completely upside down, but I haven’t noticed anything dripping out of mine when I flip it over. Also, it seals so well that if you have the slide closed, you can hear it! And yet it’s still easy to clean. They are excellent quality and I mainly bought this because the other kid I had, had a plastic slide that would close every time I went to take a drink so I had to keep holding it open. These lids are SO much better. They only slide open and shut when I want them to. If I need more in the future, I know where to get them from. Highly recommend.

Got these for my Kodi cup, it's a little loose in the cup but there is no leakage when I drink. I can hold the cup upside down with water filled inside and it hardly drips, so I am confident that if it were knocked over there would be minimal spillage. UPDATE: 2 YEARS LATER!! I'm coming back to buy more of these, as I've since gotten married and we are using these lids a lot more often! The lids we have get daily use, and after 2 years, they are still just as good as the day I got them in the mail. Over those years, there have been many moments where the cup is tipped over, or we drive over a big bump in the road. In either of these situations you'd expect a big spill, but with these lids, not a drop escaped! I am choosing to buy from this manufacturer specifically because of how pleased I am with the product.

I bought a few insulated stainless steel coffee mugs from 2 different vendors. I believe they are 12 or 14 oz. capacity. They are easy to use and clean, but the one kind just has an always open drink hole, and the other has a plastic slider lid that does not move smoothly. I just got these new lids and they are great. I ordered the '20 oz' size and it fits these 12-14 oz. mugs perfectly. The slider moves easily and clicks shut. It appears there is a magnet holding the slider portion on, you can slide it forward then push it up from the bottom to remove it to clean it thoroughly. Now my coffee stays warmer without an open hole. The lid material feels thick and sturdy, and the rubber gasket has a double ring of rubber to seal well. I wish the default mugs came with this lid, it is good.

I didn’t like that I ordered lids that looked very similar to a stock yeti Tumblr magnet lid. But they work just fine. The look doesn’t bother me much at all. The only thing I don’t like about the product is that the lid is more prone to splattering when you close it after taking a drink. my other yeti lids rarely do it. But these are aftermarket and good for the price.

This is a good product but not as good as the original purchased with tumbler I found some of them leaked
