Spill-Proof Magnetic Slider Tumbler Lid Replacement - Compatible with Rambler & 20oz/30oz Tumblers - Durable Black Lid Set (2Pcs) for Hot/Cold Drinks - Perfect for Travel, Office & Outdoor Activities

I would say that these are just as good as my original Yeti lid. Perfect fit. If you hold the cup sideways (closed) liquid will dribble out a little. That's not a problem for me. My 20oz tumbler fell off a table in the yard. Didn't spill a drop.I would definitely buy it again.Fits almost every travel cup/mug/tumbler that I have (and I have too many). Love that it is easy to clean. I'm going to toss my old ones that don't come apart and can't be cleaned. These are perfect!I can hold the cup upside down and nothing drips out! Well worth the cost. I tried cheaper ones that just didn't do the job. I would buy them again.These replacement lids fit better than the Ones that came on the YetiVery good replacement lids.After my dog ruined one of my YETI tumbler lids, I chose these as a replacement with spare. They’ve worked out great - work as well as original lid.These are so simple. They fit great, they stay closed. I can take my coffee from my car, across a big parking lot, and up a ton of stairs, without worry that it will jiggle and leak. They are super-easy to take apart and thoroughly clean by hand. I don’t have a dishwasher, and most slide-open lids hide too many places for old coffee to accumulate. No tools necessary, and the magnet design is such that continuous use is not going to make it loosen up. I’m ridiculously pleased with these lids!None of these lids are perfectly leak proof, but this one is closer! And it is solid. I've gone through 4 other lids in a year....they keep cracking in half. This one is easy to clean and looks like it will last
