Review on Coffee Mug Warmer: Smart Electric Thermostat Coaster for Hot Coffee Milk Tea Water Cocoa, Desk Office Use - Beverage Heating Plate with Auto Shut off, Candle Wax Cup Warmer, Black - Perfect Christmas Birthday Gift by Travis Coffman

I love this cup warmer! It's pretty cold in my office in the winter, which means my warm drinks only stay warm for a few minutes. I was worried this warmer wouldn't keep my drinks hot enough, but that's for sure! Even hot! I can even have a cold drink in minutes with this thing. The pressure sensor requires some weight to activate, so it is not suitable for very small or light mugs as they may not be heavy enough. I use a large, heavy, flat-bottomed ceramic mug and it's perfect!
