Keeps my coffee/tea hot all day.
The Mr. Coffee Mug Warmer lives up to it's name. When I place my mug of hot liquid on the warmer, it keeps it warm all day. I use it at work, and it is discreet looking, safe, works extremely well. Initially, it will not heat up the contents of the mug enough to my taste, however, it will maintain the warm temperature all day.
