YETI Rambler 20 oz Tumbler, Stainless Steel, Vacuum Insulated with MagSlider Lid

I received my Yeti 20oz with Mugslider lid. Looks great, well built. But after a hour or two, coffee is cold. While driving, the coffee will leak past the lid, and proceed to drip, all over your cars interior. I was hoping for something better. I also liked the information pamphlet that can with the cup talking about liquid viscosity, and how cold liquid is thicker, than hot, so hot liquid will have a tendency to leak around our Mugslider lids. Here's and idea, how about making a lid that doesn't leak when you put hot liquid in a cup??? I digress, TLDR don't buy if you want to use it for hot liquid i.e. coffee.

Counterfeit piece of junk! The rambler pictured shows the magnetic slider lid. The rambler I received shipped from China and came with a cheap piece of plastic lid with no magnetic closure. I do not believe the tumbler is even vacuum sealed as hot coffee turns cold in a matter of minutes. It is deplorable that Amazon allows counterfeit sales like this.

I ordered the Yeti Rambler 20 oz with the MagSlide Lid. Although the package description says “w/ MagSlide Lid”, the tumbler came with a regular lid. Very disappointing!

The product description states it is a yeti cup with a mag slider lid. All that was included was a cheap off brand plastic lid! I ordered two feeling I was getting the mag slider lid as well! Disappointed!

I was spooked by the warnings of ''Fake Yeti'' cups. I don't think any of these are made in Texas any longer, although they once were, hence the warnings about fakes. My local ACE Hardware sells the complete line of Yeti products. I checked a bunch of those, and all were ''Fake'' according to some of these warnings. I decided to order from Amazon simply so I could get the nice aqua-blue color -- and to get the nifty sliding cover, which my ACE does not carry. The color is beautiful, and the sliding cover is nearly -- though not completely -- leak proof. The cover seals well enough for my purposes, which is to rest in the truck cup holder. Yeti makes cups with screw on tops which could be dropped into a backpack. I could buy one of those from the local ACE if I ever need one. Photo included. Notice I have washed the YETI and have removed the cap so that it can evaporate and dry here on the kitchen counter-top in my photo.

Came with two lids, but neither was the magslider and both were cracked. Overall, pretty unsatisfied.

My cup leaks. When I tilt the cup to take a sip the liquid gets under the lid and seal and drips all over me. I'm super bummed. The cup is Super pretty and keeps my cold coffee cold but I just dripped coffee down my shirt and it's not the first time. I checked about exchanging it and apparently I'm a couple of days late for that. I'd buy this again if it weren't making a mess everywhere and ruining my clothes. I'm assuming this is a glitch because everybody else has such positive reviews. I emailed about an exchange, fingers crossed. EDIT: I wrote an email and got a very quick response. They sent me a new lid and it has changed my life. haha I could tell as soon as I put the lid on that it fit differently and it would seal. And it does! I love my cup, I love their customer service.

I purchased a few Yetis stateside which have the real mag slider. This mug is counterfeit from China.
