Tumbler Lids Spillproof for 20oz 30oz Yeti and More Cooler Cup, Splash Resistant Lids for Tumbler/For Yeti/Ozark Trails and More, Splash Proof Open - Close Slide Lid, Straw Friendly (20 oz)

It was aperfect fit for my Nurse Tumbler.

Cap was shipped in a timely matter. Cap fits on my husband's coffee mug perfectly.

Perfect fit

This lid is well made, but it did not fit the item someone suggested it for (Brumate Juggernaut when hacked).

Says they are compatible with Swigs. The slide also doesn’t stay locked because there is no lock. Don’t tip over the mug or put your finger on the edge. The top will fall off. It is NOT compatible with Swigs. Wish I could send it back. Waste of money.

I dropped my cup at work and the lid broke. That part doesn't sound like a glowing review but up until then, the lid was work exactly as you'd hope. There are even a few times when I was driving in my car and the cup toppled over; barely any liquid came out so clean up wasn't so bad (it helps that I mostly use this as a water cup).This thing works as advertised, it allows me to take my cup on public transportation (which thankfully I don't have to do often any more) and it is an upgrade from the lid the cup normally comes with; all at a great price.

a little pricey - but fits a wide variety of tumblers

Not a huge fan of this item. Purchased to replace the original lid on an insulated tumbler I have been using for over three years. This is pretty much an exact replacement for my original lid. At the time I purchased this product, I also purchased another lid from another brand. The other lid produced a more positive seal around the sliding mechanism. Would still like to find a lid that is more easily cleanable. I’ve broken lids from two different brands trying to safely remove the sliding mechanism and clean beneath that. Lid seals tightly around perimeter, but sliding mechanism seals poorly. If leak proof is what you need, this is not the product you want. Attached pics are with lid in closed position.
