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 6/6/23These 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.

I lost the magnet slider for my yeti cup awhile ago. I was very excited to find this replacement lid! It fits, and works perfectly with my 30 oz cup. It also fits another 30 oz cup I have (BJPKPK) that I like, but the Yeti lid is far superior to the one it came with. I wish it came in bigger sizes to fit my other tumblers!!

These replacement caps fit my 20 oz tumbler perfectly! The slider cover is attached by magnets and slides open or closed smoothly, with no leaks when closed. I highly recommend these covers!

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.

For the 20oz Tumbler they fit as good as the factory, but two downsides. First the mag slider feels cheaper than the original, although this is minor. Second the diameter is slightly undersized - the inside seal is fine but it the outer lip doesn't quite line up with the outside of the mug - about 1mm all around. Again it seals still inside so no issue there, but I'd be tempted to just buy the original next time as this only was $2 cheaper per lid.

I got these as replacement lids and they fit great. I like them even better than the original lids because these can close. They helped keep my coffee hot for hours when normally the hole in the original lid lets it cool, and also lets it spill.

Fits great

Sturdy and fun colors. Dishwasher safe, works very well!
