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 Mike Barnett

I wish it had higher settings or at least more options. There are no switches to turn on or off. I use a regular glass coffee mug and it's ok. When the cup is full it stays warm but not hot, half warmer but if I stir it it gets warmer. I'd say there's a quarter cup left and it's hot, but the A/C blows on it all the time, which is why I bought it. I can't walk in bed like this and always ask for a warm-up on the mic. In the end, after the third time, the coffee became disgusting, and I didn't even drink half until a new one was made for me, and now I drink it all. I make coffee with milk instead of water, so I'm not sure if that doesn't make it as hot as I'd like, but it's definitely plausible, and I haven't tried water-based hot beverages with it yet. I got the white one because if you put a cup on it it turns itself on and has a purple light around it to let you know it's on. I turn it upside down when not in use in case something falls on it or a cat steps on it by accidentally turning it on because it heats up pretty quickly. Keep it on a flat table with nothing underneath, such as a a carpet or tablecloth, as it will not turn on when resting on it. I've only been using it for a month, but I use it almost all the time. I will buy it again if something happens to it because for the money it's worth it's pretty good.
