Spill Proof Lid With Straw For 20 Oz YETI Rambler,SOEOR Tumbler,RTIC Cooler, Ozark Trail cup and other brands Vacuum insulation stainless steel 20 oz Tumblers

Does not fit Yeti 20oz Rambler; it doesn't even seal. Just sits on top and lifts right out with no effort. Do not waste your money on this oneThis is an update: to the above review. The supplier explained they had an issue with the manufacturer and sent me a new cap with straw even after I returned the product for a refund. Not only did I get a refund, but I received the new cap and straw and it seals like it should. Loving it and definitely would buy from this supplier again; they stand by their word and want their customers to be happy!

I was so nervous this wouldn't fit the tumbler I received as a gift. It fits perfectly.

Highly Recommend!

It’s great it only leaks a couple drops through the straw hole but you’d have to have it sideways. it’s slightly too big for the 20oz so it doesn’t push down all the way. It still keeps the liquid in the cup but it’s kinda annoying

Okay. I’m coffee OBSESSED. Seriously, it’s a problem. The coffee shops are discontinuing styrofoam cups and replacing them with paper. The paper doesn’t hold the coffee heat more than a half hour. So I bought a yeti. Better for the environment anyway. So I bought this lid for my Yeti. While I don’t think this lid is leak *proof* (hence the 3/5 on the “Leak Proof”claim) I CAN verify, that it is resistant to splash-outs, in a cup holder, going over a pothole ridden road up here in Massachusetts. If you’ve ever driven up here, with a coffee, you KNOW what I’m talking about. Between construction, potholes, and the terrible drivers, you’re bound to make a mess down the cup, and into the cup holder. I had NO nasty sticky mess with this lid. At all.I’m going to be honest, I didn’t compare it with the Yeti equivalent. I didn’t want to bother with the yeti lid because this had better and more explained reviews. I also am very happy it came with the brush.I can say, that the suction of this lid is equal, if not better than the magnetic lid that came with my cup.I tested how long hot drinks stay hot with this lid (just for my own reference, not many people brave straws with hot liquids.) Coffee bought at 6:15am was still steaming, when I took the lid off, at 10:45.Around noon, it was the ideal temp for me to drink my coffee. (I can’t drink it when it’s so hot. Less than piping hot, more than warm is my ideal.)I have also tested iced coffee, with the ice holding up until well after 4pm which is beyond ridiculous to me. (In a good way) I have four kids and I am often interrupted and forget I have a coffee. So keeping the temp and ice relatively unscathed is awesome.So the integrity of the cup holding temp isn’t really hindered by the straw or straw hole, in my opinion.Overall, I’d buy again. And plan on buying the next size up for my husbands yeti that I bought him.
