NEW Spill Proof Lid for 30 oz YETI Rambler Tumbler, RTIC, Ozark Trail, and other 30oz stainless steel tumblers | Colored leakproof travel lids (Red)

Good product and works well with Costco bought thermo cup.

The locking flip lid and spill proof seal are great, however the hinge attaching the flip lid has broken on 2 lids since Christmas which makes me wonder about the others that I gave as gifts.

This lid made my Yeti 30oz perfect! I have been using it daily for a few weeks now. The spill proof works but I was concerned about how well the friction seal would hold if the Yeti fell over. Yesterday morning I put the coffee filled 30 oz Yeti in a too small rear seat cup holder and went back in the house to find a few other items I needed to bring with me. Ended up taking about 15 minutes and when I came out and reached to the back seat, I could not find my coffee. I got out to open the back door and saw it laying on its side in the seat. It had fallen about a foot from the fold down cup holder. I had a bad feeling I would start the day without coffee... and be sopping up 30 ounces of coffee with cream from the cloth seat of the rental car. Well, first I was pleased as I picked up the cup that it looked like Imstill had a fair amount of coffee. Then I was really pleased when I recognized that not a drop had spilled and the seat was perfectly dry. It had to have been laying their for 10-15 minutes. So this thing works very well and the top won't come off from a short fall. My only complaint is that the folded back stopper sometimes gets a little moisture on my nose... but that is way better than the drops of coffee on my shirt from the original Yeti, non-sealing lid. Great purchase. Well made.. I'd buy it again... if it ever breaks

Great product! I ordered two and gave one to my husband. He wasn't happy with his because the liquid didn't come out fast enough to suit him. I have no complaint with the volume coming through the lid. It seems that I am always fumbling with full tumblers, a purse, bags of groceries, etc. This has been a great purchase. It has tipped over in our car with undersized cup holders multiple times, and hasn't spilled a drop. I absolutely love it, and I like to support small businesses and veterans. You do need to have the cover open when you place the lid onto the tumbler because of the tight seal. It will not seal properly otherwise.I want to order two more for my other tumblers. I hope colors other than red and light blue will be available soon.

Not leak proof but leak resistant pours slot slower and my nose hits the the cap part not a fan

***Update*** Had to come back to say how awesome customer service is with this company. I don't know what happened to the hinge on mine but after 4 months of daily use, it wasn't seating correctly. I wrote to ask if they knew of it being an issue(not griping.) They apologized, acknowledged it was probably a defect and immediately said they would replace it! Not only did they replace it but they sent an extra for me. AWESOME!Fantastic product! I have a 30 oz Ozark Trail Stainless Tumbler and this fits perfect. I constantly was having coffee splash out or once in awhile, I would knock it over but this prevents ANY leaks! The photo is proof! From a Marine Veteran to this Veteran owned company... awesome job!

Hat to call it Junk and always want to support Vets but I am SO disapointed the 2nd time I used the lid the stopper broke off!!!

The cap on it was broken out of the box. It will not accommodate most straws. I drilled it out so that it will accommodate straws fortunately since the Cat broke off didn't make much difference if I did so.
