Review on ENIGMA Smart Coffee Mug Warmer Digital LCD - Auto Shut Off Electric Cup Heater for Desk - Candle Wax Heating Plate for Beverage, Milk, Tea & Chocolate - Adjustable 3 Temperature Settings by Marvella Griffin

I work at my desk all day and have coffee on hand most of the day. I had an old heating pad but it no longer kept my coffee at 150ºF so I bought this one. It doesn't work, actually doesn't work as well as the one I had over 10 years ago. i will return it If you google "What temperature does coffee taste best at?" you get from 155ºF to 175ºF. 120ºF tastes like lukewarm stuff.
