I love this mug. No matter the weather, I love a hot cup of coffee. What I'm famous gor, is forgetting I had a hot cup of coffee, and I end up with this room temperature, nasty drink. Microwaved coffee is just not the same.  This is perfect. I set my temp, for hours I have a drink at the perfect temp. The lid makes it even better, I don't have to worry about what could be in my coffee. The charging dock sits perfectly on my desk.
