KEEP LOOKING
Color: Black
I have used a coffee mug warmer all of my long adult life. This one is the worst. I had to get a new one because my new coffee mugs were too big to fit on the old warmer. Yes this is large and will fit most cups I would think. But the amount of attention this thing requires is ridiculous. No simple on/off switch and leave it and forget it. You have to keep touching points in order to find the on and off area, and then you have to keep tapping it to get the temperature you want, but if you take your cup off and put it back, the temperature goes back to the lowest and starts blinking until you tap it to make it solid at the temperature you want. I got it yesterday and it’s going back today. Trust me on this you won’t like the attention it requires.

Too big, gets hot on bottom
Color: Black
After receiving this, I see it's frequently returned. I wish I didn't buy it. It's too large for my space where I kept my previous warmer and I tried it out; it got quite hot on the bottom. Nothing great about it. I'm boxing it back up and back to the drawing board.

Great
Color: Silver
This coffee and tea warmer is an absolute game-changer! I work from home and love keeping my beverages hot throughout the day. This device truly lives up to its promises. It heats up incredibly quickly and maintains a consistent temperature, keeping my drinks warm for the price. I can’t find a better option, and the auto-shut-off feature is a huge plus. The temperature control is precise, and it actually performs as advertised. I highly recommend this product for its affordability, multiple temperature settings, and reliable performance. It has everything I was looking for in a coffee and tea warmer. The previous one I had worked well and had an auto-shut-off, but I kept accidentally shaking the cup, causing it to spill and melt. This one seems to be well-constructed and definitely worth the investment.

No more cold coffee!
Color: Silver
Great price for all the nifty features - timer, auto shut-off, hot and hotter! Large button icons and digital temperature display are easy to see. My coffee and tea stay hot enough to drink without making multiple trips to the microwave because I got busy and let it get cold. New best friend!

i can’t believe how long i went without this
Color: Silver, Color: Silver
i never expected how much of a difference this item would or could make in my nightly tea routine.
i’m a slow sipper and would normally have to get up and microwave my mug 1-2 times depending on how willing i was to stop everything i was doing and move out of my comfy spot to remedy the impending sad lukewarm experience. YALL! the temperature really does make it taste better (i already knew that) but now i can settle into my spot in cozy PEACE and take as long as i want to to enjoy my tea.
i was worried if the lower price point compared to other options on amazon would mean it may be lacking in quality or function, but NOPE! just a genuinely good deal (about $10 at the time of this review) and the features are all there. yes yes yes, go ahead and treat yourself because this one is worth it.
