Warm your mug first with hot water. Keep coffee at an acceptable temperature.

No problems with this coaster other than it would be great to have an on/off switch to use as a coaster for cold drinks as well.

It keeps my coffee nice & hot on my desk. That's what it's designed to do. I especially appreciate the fact that to turn it on, all I have to do is put my coffee on it. Keep in mind that my coffee is already hot (I read where some moron complained about it not heating up a cold beverage), and this warmer keeps it that way. I'm very pleased with the price and the product.

The Coffee Mug Warmer with the Stainless Steel Mug is very practical in an office setting whether at work or I can imagine at home too. The mug being stainless steel seems to transfer the heat from the Coffee Mug Warmer pretty well, keeping the fluid warm for as long as I want. Kinda feels like camping when drinking from stainless steel, but that is ok, as it serves as a great reminder during the colder months. The warmer operates pretty fast and well.

I bought this because I always end up with a cold cup of coffee or tea at work so I needed something to keep them warm. Turned on when a full cup of coffee was placed on it and shut off when the cup was 3/4 empty. I was able to use it with a variety of cups including a paper To Go cup. It’s nice that the cup base doesn’t have to be a specific size or shape for it to work.

This is the best coffee cup warmer I have ever tried. It has an automatic on/off feature as the cup is placed/removed from the warmer so you will have no concern about forgetting to turn it off when you are done.

I bought this to replace my previous coffee warmer. My old one has broken and looks really ugly. So I decided spent a little more money on a nicer looking one, and ordered this model.After a week of use, I want to share some of my experience. Firstly,as it's description this coffee warmer can keep your coffee, milk, tea and other beverage warm.I have measured it with a thermometer,The maximum heating temperature of this warmer plate can reach about 125°F. If you want it to heat your coffee very hot, you may need a microwave or kettle. Anyway, i satisfied with it, Because I dislike to re-heat my coffee again and again, and I don't like to drink too hot coffee,I have burned my mouth before. This is the best one for me. Secondly, I so like auto shut off features. it very easy to use, This coffee warmer will automatically turn on when you put mug on it, and will shut off when you take mug away. plug the cord into outlet, and you needn't pull out every day. It very safe and reliable, But be sure to take the cup away when you needn't use it, otherwise the drinks will all evaporate. Lastly, I like its Iphone style design. Looks so beautiful, It's really like an ornament on my desk.

I'm impressed with this little gadget. There is a small switch in the bottom which triggers it on or off depending on if a cup is weighing it down. It's a novel approach that works great. An empty ceramic coffee mug isn't quite enough to trigger it, but once there is about 1/5th cup of fluid it turns on. Nicely done. You can always put the mug closer to the front or further to the rear to fine tune when it will turn on. The surface area is ample. Otherwise it really cooks and keeps coffee hot while using only 16W of energy. It's all around a perfect desktop coffee warmer.

I drink tea every night, for several hours. But, I hate it when my tea goes cold. This product is great. Love the automatic on/off safety. I have a very large tea cup and sometimes I put it on the warmer before I even put any liquid in it. It warms my cup. Then, I put the tea into the cup steaming hot and the warmer keeps my tea at the perfect drinking temperature, even in my very large cup. Very easy to use. Attractive and easy to clean. I looked at many before I made my selection and I am very happy with it. I use it almost every night.

Honestly a little in love with this thing. I bought one for my office because it's an ice box and my coffee always gets cold like three minutes after it's made, but this little guy does the trick. Keeps it warm (not hot, but definitely a solid temp). Also looks pretty low-key on the desk so you don't get questionable looks from coworkers. I've been using it for a few weeks now and love it so much I just got one for my apartment.
