Magnetic Spill Proof Slider Lid, ALIENSX Replacement Lids for Yeti Rambler, Ozark Trail,Beast, Old Style Rtic Coffee Tumbler (30 oz - 2 Pack)

I love this lid. It fits well on my tumbler and is easy to get apart to clean. Plus the magnet snaps the slider in place to keep it open when you're drinking and closed when your not.

My first ever Yeti (Rambler 30oz) leaked from day one so I never understood the brand's hype. Yeti's warranty would only be honored if I shipped my mug to them so they could inspect it and determine if their product was faulty -- yeah right, like I'm taking that chance. I always drank without the lid on or used a straw so that my drink didn't dribble onto my shirt. I'm so happy now to have a lid that fits and doesn't leak and a bonus that the magnet slide is so easy to clean.

Fit my yeti cup perfectly!

I bought this for a random coffee mug I also got on Amazon, but which came with a really poor lid. I also own a yeti cup and liked that lid a lot. This lid does fit both cups perfectly. The sliding top is magnetic and easily removable for cleaning, the rubber/silicone seal feels secure and I haven't had any issues yet, even washing in the dishwasher.There is a small hole hidden under the cap so when the lid is open and you're drinking, it lets air into the cup and prevents the "glug". I actually did not notice this hole for a long while until one day during cleaning. I appreciate how cleverly it is hidden.However - it is *not* leak proof. I would call it *resistant*. If you knock your cup over or tilt it, it will *drip* albeit slowly. Basically the magnet is not as strong as Yeti's offerings. This will save a computer if you knock a cup over, but likely not paper as a couple drops will leak. If this fell over in a bag or was left for a while, the cup would likely empty everywhere, possibly ruining whatever.Despite that, I use it carefully and have no real issues. Just take above into consideration.

Love these lids. I can take the magnetic piece off and wash underneath. Will never buy the sliding lids again. These are fantastic!
