2pcs 30oz Splash Proof

They fit very well on all of my mugs!

Product fits perfect and makes the coffee mugs work like new

As described. Fits the Yeti

Perfect fit and seals great. The slide is plastic on plastic so it needs to be handled gingerly. I use Pam to keep it smooth. Be careful with oversized straws. I have a metal one but it the conventional size. Good value for the money and I have a spare.

Good seal-works we’ll!

I work in bumpy machinery and or trucks all day. These lids do stop spills from shaking - but IMO they are pretty cheaply made and don't stay open or closed completely.

The media could not be loaded.  These fit very tightly into the yeti mugs. I really like the cover. I wash it all the time in my dishwasher has a sanitary rent so it gets pretty hot. We have not worked or had any damage. The slider is not rubberized though and so isn’t totally leak-proof although it does block a lot of splash. If it tipped over only a little tiny bit would come out

EDIT: After a solid trial of several weeks’ use, I’ve concluded that the sip hole is a fatal flaw. Even if you manage to never tip your tumbler, the sliding cover for the sip hole provides no meaningful protection. Today, a minor bump to the elbow caused a jet of coffee to splash onto my shirt, because the cover doesn’t click into place, and had slid open unbeknownst to me (so I’ll work a full shift with a coffee stain on my shirt, boo!). This lid is helpful in providing a basic cover over your mug, but is not effective if you’re on the go. I would not buy it again. ORIGINAL POST: Bought these as a replace lids for my 20 ounce tumblers. They are adequate in that they fit well and the gasket seems to provide a good seal. The flaw in this replacement cap is in the sliding cover for the sip hole. It’s provides little/no significant protection if the tumbler tips over- which mine did. Even though I was quick to set it straight again, a couple ounces bubbled out of the useless slide cover over the sip hole. I’m going to look for a better option.

Forget Yeti etc. These things shine brightest in Ember mugs and double their use time.

Comes apart so you can clean coffee out of it👍

Just like the real thing except the slider does not prevent spilling. Liquid still leaks out if the cup tips over even with the slider closed. 🤷‍♀️ great for the car but not so good in a purse.

These lids are a good quality. They provide a very tight seal to both my 30 oz Yeti, asa well as, another 30 oz coffee mug called “the Rocky Mountain Tumbler”. I am really delighted with the product and highly recommend it.

Not really dishwasher safe and cracked after about a month.
