Review on 🥤 YETI Rambler Vacuum Insulated Tumbler: Unmatched Lid-secured Versatility by Damon Fuqua

Amazing mug keeps my ice water cold all day plus. I fill this cup with ice and water around 6:00 a.m. and when I go to bed it's still mostly ice. The next morning there is even ice in the cup. I don't know what scientific magic is causing this, but this is the most insulated mug I've ever used. The only reason this isn't a 5 star rating is that after about a month of use the cup lid lost its ability to form a good seal. This doesn't affect the mug's insulating ability, but it does result in a bit of liquid seeping through the poor seal with each sip, making it almost useless. I hand wash the mug and lid every time so they don't get damaged in the dishwasher. For such an expensive mug, it's a shame it doesn't have a better lid. Update to my review: After much disappointment with a leaking cap, I ordered another replacement cap for the Yeti. Exactly the same problem right out of the box. This mug is great, but without a working lid it's useless as a travel mug. Completely unacceptable for such an expensive mug. Try another (cheaper) brand.
