Great seal would buy again

The lids are good!

If I could give this a zero star I would they broke very easily i pick it up and the slider just fell off and the one that did not break it keeps closing when im taking a drink I would not take this product for free much less ever buy it again and I usually don't do product reviews but this was such a waste of money I wish I never had bought

I love these lids. They do fit and make a tight seal and rip resistance. It prevents spills even when you accidentally drop or knock your tumbler down. It helps retain heat relatively long time as long as the sliding cover is closed, which also easily slides open and close. I have been using them since and no major complaints except for the nuisance of liquid getting trapped inside the sliding covers. It looks dirty even when it's clean especially when coffee is trapped there. It's also hard to clean and removing the sliding covers are a pain. It's recommended to soak it to remove trapped "debris" but that doesn't work a whole lot of times. Removing it is the only solution every time but you have to be very careful removing it or you'll break the thin "hook" holding it in place. Other than that, it's a great buy for me.

good

Fit the cups I have. Fits and no leak. The slide was tricky to get used to…you need to put pressure down as you slide the sip cover. Excellent product.

I put the lid on my mug, worked great. Used 1st one with hot beverages and slide fell out. One out would not stay in. Second lid I used about 2 weeks with hot beverages and slide and entire slide piece and snap in area shattered and fell apart. Used last 2 lids other eac one lasting no longer than one month.

These lids fit perfectly in a number of different yeti-like tumblers that I have. They absolutely help prevent leaks should the tumbler get jostled or tip over. For these reasons alone I like them But here is where the lids begin to fall a bit short... They are not easy to drink out of due to the way they are ventilated (this same design is part of the reason they do not leak). You cannot open the slider completely or you will get a weak and very slow-flow. You have to open it about 85-90% to get the best, drinkable flow. Obviously temperature of your coffee might make a slow-flow more or less advantageous. I like cold coffee... I want a decent swig without having to find the sweet spot on the slider. The other problem is that with hot coffee, the steam builds up pressure. When you open the slider, a small spritz of coffee is ejected from the spout. It does get all over your shirt, your car, your desk. Its a minor inconvinience but definitely annoying. lastly... due to the leak-proof design... the lid is very difficult to get completely clean. I do recommend these lids as long as you can tolerate some of the short-comings.
