content: I ordered a 12 ounce, Highwave Original Autotray Stoneware Mug at Amazon.com, because I love mine and wanted my husband to have his own. (He kept borrowing mine!) At first, WinningGifts sent the wrong mug but made good on their mistake. They were very helpful and friendly, let me keep the other stoneware mug and also sent, for no extra charge, a navy blue (my choice) autotray mug within a few days. As it turned out, my husband loved the navy blue mug better than the white. Coffee tastes a lot better in the stoneware mug than in stainless steel or plastic. The mug also has a nice weight and simple, classy design. Coffee does not stay as warm as it would in a Thermos-type container, but for our purposes, that's fine. The only drawback to the design is that the stoneware mug is breakable. (My husband dropped his first Highwave Autotray mug.) So, if you get one, you'll want to be more careful with what will become your favorite travel mug.
