Review on Tervis 1299955 Pittsburgh Steelers Stainless by Eric Smithlin

I bought this product together with YETI, about the same size (slightly smaller). I tested them by putting cold and hot drinks on both and the YETI kept them warm for about 3-4 hours, but this mug kept it that way for hours (dare I say 8-9 hours), of course for cold drinks. the ice melted, but it was still colder than the YETI cup. Nobody paid me to say this, but I think it's good to know given the current price of YETI mugs. When you close the mug, you can even feel the airtight pressure of the mug.
