Smart Beverage Heating Plate Candle Wax Cup Warmer Electric Thermostat Coaster for Hot Coffee Milk Tea Water Cocoa Desk Home Office Use (R1 Black)

turns off when one lifts the coffee cup. nice glow when heating. strong enough heating element. good price

It works wonderfully. It keeps my coffee warm all day if needed. I definitely recommend this warmer.

Absolutely love this!! It works so great. Keeps my drinks hot until I lift it up. No on and off switch to worry about. I’ve even used it to melt a candle in the office since I can’t use a flame. I now have two (one at home and one in the office) and I’ve even given it as a gift to two different people.

I like it but it doesn’t have a shut off switch or automatic shut off if left on. I unplug it when not it use because if anything gets put on it by mistake it will heat up

Probably my favorite impulse buy! I use this every single day - keeps my large coffee warm while I work. It actually can heat up my drink too much if I forget it's there, but not so hot to be dangerous. Cord length is plenty. Sturdy.

Easy to assemble works great good price.

This works great to keep a cup of tea or coffee warm for hours. Plug it in, and it turns on when you place a cup on it, and it turns off when you remove the cup.

I’ve had this mug warmer for a couple of years. In fact, it’s sitting in front of me right now. It definitely keeps your coffee warm. However, my experience is that the longer the mug sits on the warmer, and as the quantity of liquid in the mug lessens (as you drink it), the coffee gets hotter and hotter until it’s painful to drink. I ran across the listing for this warmer when I was looking for a warmer with temperature controls, and was surprised to see it described as holding a constant temperature. It doesn’t.I often take a long time to drink a mug of coffee, as I’m browsing online or trying to solve a New York Times puzzle, so my coffee has time to get unpleasantly hot. If you’re more of a fast drinker, this warmer may work well for you. If it weren’t for the getting too hot problem, I’d be happy with this warmer. The auto-on/off is nice, as is the light that tells you when it’s on.
