Review on Convenient Coffee Mug Warmer: Auto Shut Off, Ideal for Desk Office and Home Use by David Robinson

My coffee got cold on this "warmer". I bought it because of the auto shut off feature. The idea is good, but the implementation requires work. It turns off when you pick up a cup and turns on again when you put the cup back on the table. So the heating pad doesn't really have time to warm up your drink. Another downside is the short power cord. I have it on the table and the surge protector is on the floor so the plug barely reaches it. I go back to my Mr Coffee mug warmer which works great. This one returns.
