Great mug warmer with temp control
Color: Black
I replaced a cheap mug warmer with a couple of these for the house, and for almost the same price this is a lot more functional. I really like the temperature control and silicone surface protector. In combination with the carafe below, this has changed my life - no more microwaving coffee all morning.

Super Satisfied Customer Here!
Color: Gold, Color: Gold
I purchased the gold/black mug warmer. I always spend a good about of money for great coffee products and I take my time to perfect my coffee for my mornings at work. However, I get pulled into urgent meetings and just something urgent and I always leave more than half of my coffee behind. When I come back it’s cold and that’s very disappointing considering the money and time I spent to make it bc I then have to toss it. I don’t believe in microwaves and I refuse to use one. When I found this, I was super excited! It looks perfect at my desk and it works perfect! I would have liked it to be more on the brass gold like my pen holder, but it’s just as pretty! As you can see, my mug had a layer on the bottom and that made me think it may not work well, but it did the job. My coffee was super warm and it got even hotter as I left it there tearing it. I turned it one before making my coffee, so I’m not sure exactly how long it took to warm up but for me, by the time I got back, it was the peg temperature. I highly recommend this to anyone who has the same struggles. No more cold coffees! Thank you!!!

Works great, easy, convenient, safe and priced right
Color: Black
This warmer is just amazing. I tend to nurse a mug of tea from morning to night. This warmer has three different temperatures. I always start out at the high 167 but as I drink my tea and there’s less than a cup, I drop it to 149, and when it gets lower, I can drop it to 131. Keeps it at the right temperature all day long. One of the other things I love about it is that if I leave and forget that I still had some tea sitting there, it turns itself off after four hours. It is so convenient to use because you don’t have to turn it on or off. You just set your cup down on it and it automatically returns to the last temperature you used. I bought my first one in 2021 and now have five of them. I keep one in my bedroom, one in my family room for when I’m watching TV, one at my office desk, one at my partner‘s desk in his man cave, and one in the camper. I’ve tried many different brands and styles in the past and I can assure you this is the best. Enjoy.

Game changer for hot drinks
Color: Black
This coffee mug warmer works great and keeps my coffee at the perfect temperature without overheating. Love the choice in temperatures feature. It’s simple to use, heats quickly, and fits my mugs well. A great upgrade for enjoying hot coffee longer at my work desk.

THE ABSOLUTE BEST MUG WARMER! WORKS PERFECTLY!
Color: Black
This is the best mug warmer I've ever had! It's sleek, keeps drink hot or even warm if that's what you prefer. I bought two, my niece liked mine so much she got one, and I'm getting one for my guest who comes to my house.
