I have tried Yeti and several Yeti knockoffs like the RTIC, Nigloo, (no, I did not mean Igloo), Orca, and Ozark Trail. They all do the same thing. In fact Yeti is now slashing prices on a lot of stuff due to their competition. As long as it's a double walled stainless steel (Most are 18/8) tumbler then you should be good to go. Wal-Mart is now even selling the 20 and 30 oz ones in a powdered color for the same price.
