I’ve been using this for several weeks now at home to keep my coffee warm while I’m reading. Works great. Best if you put a cover on a full cup but the cover is unnecessary when the cup is half or less full. It’s a pressure sensitive plate so you have to be careful not to put anything on top of it when you don’t want it heating. The cord is a little short for using on my coffee table but it’s probably perfect for a desk. It’s good enough that I’m buying another for a friend.

Love the design of the mug. Fits so comfortably in the hand. The warmer keeps coffee/tea/cocoa at a perfect temperature.

I was sort of worried that I needed to stick go the mug provided but this works on all of mine :) it really makes your mug hot tho so I wouldn't recommend forgetting it on the warmer all day, just nice for long study sessions...

I love this! I drink tea at night in bed while reading or watching a show and now I never have to worry about it getting cold. I was so surprised when I got this because I didn't realize it was coming with a mug - such cute packaging!

I got this for my mom for Mother's Day and she loved it! She said she can walk away and forget about her coffee for hours, but comes back and it is still nice and warm! Just be aware that this is not wireless device.

I bought one of these for my mom for Mother's Day and she loved it! She raved about how it kept her coffee at a good temp all day and the more she drank the beverage the warmer it got. So I decided to purchase one for myself and I have to say I really like it. My tea stayed a great temp for the 45 mins I sipped on it. It turns on by sitting the cup on it so I would be careful to keep things away from it that could cause it to activate the warmer. Love it! Definitely my go to gift option this year!

This works just like it says it does...Just be sure to place it on a flat surface. I had it sitting on a table runner at first and it wasn't able to sense the coffee mug on top of it. Then, when I placed it right on the table itself, it worked perfectly. It keeps the coffee at a constant drinkable temperature. I love it!

I was kind of skeptical about how this would work but I am pleasantly surprised! It keeps my coffee at the perfect temperature and I don’t have to worry about reheating it! Everyone in my house is already trying to steal it! Great gift for coffee lovers!
