KUFUNG Tumbler Lids Spillproof 30 oz, Splash Resistant Lids for Tumbler/For Yeti and More Cooler Cup (Transparent Slide2, 30 OZ)

Ordered these replacement lids for my 30 oz water tumbler and it fits perfectly!!! No leaks and easy to remove. Made of strong material as I already dropped it by mistake, no chipping whatsoever. So happy with this purchase, very affordable and its quality is amazing.

these lids fit great on my knockoff "Yeti" cups. One is from Monoprice and one is from Harbor Freight. While they aren't completely spill-proof, they do close and keep the liquid from falling out. They can't be turned upside down and be expected not to leak but the mess will be much less if it accidently tips it won't make a huge mess and it keeps liquids from spilling as it sloshed around in the car and while you are carrying it. I prefer this over the spill proof ones as they tend to get their air holes plugged, making it hard to drink. the best part about them is they have an extended lip where you drink from which really makes it easier to drink from. I didn't know it had this but I love it.

Overall I would say these tops work pretty well, They fit my 30 ounce Tumblr perfect only because I measured them beforehand and checked the sizes in the description, which I highly recommend doing. Yes they are a bit hard to get off in the beginning when the seal is stiff, and yes somewhat occasionally the ring does pull out of its little groove but neither of these are the huge deal that people make them out in the other reviews. Again if you’re looking for perfection these are not it, but for the price point and being BPA free I think it’s a good deal in the long run……

Good Lids work great on a knockoff yeti cup.

My cup lid fits extremely well . I have had too order more than ones because I always break them . By either dropping it on the floor . Perfect fit for my tumbler

Broke my lid to my coffee cup. Fit perfectly.

The main reason for a lid is to prevent spills and leaks. This cup has an excellent rubber seal that will prevent leaks from the cup's rim..ok. However, there is a major leaking problem of leaking from under the sliding piece of the lid. Who cares how great the seal of the rim is if the cup still has leaks!! And the lid's design is just awkward and difficult to drink from, ok I could have learned to get used to that, but I refuse to give it a chance because of the leaking.

These lids are tight fitting. Unfortunately, they are so tight you have to struggle to get them off. This causes the rubber seal to dislodge and roll. Don't think they'll last as long as the original lid. Good thing they came as a 2 pack.
