Review on Coffee Mug Warmer Electric Beverage by Candice Cooksey

Not bad for a small price. It seems solidly/reliably made, the touch sensor on/off or mode switching is good. It only heats half of the glass pane. I'm not sure if this is a design flaw, intentional, or a defect. It gets very hot, but doesn't warm cups with uneven surfaces well. They say that for best results, use a flat-bottomed mug/cup with a lid. It can keep my lukewarm coffee warm and the hot coffee doesn't cool down as fast as usual, which is what I need in the end. It would be great if it worked better but I only paid about $15 for it so for that price I'm happy as long as my office doesn't catch fire.
