Great warmer that does its job
I have been using this warmer for over a year, and I am very happy with it. I don’t use flat bottom coffee cups, and my coffee cups are generally larger than a standard cup. While the black paint on top does scratch off it doesn’t deter from the warmer doing its job. It keeps my coffee drinkable temperature at work all day long. It is a size that works for most smaller areas. It works so well that I am back to buy another one for my home. I saw a comment that states that you can touch the surface. I guess you can touch it at your own risk as it will cause pain.

Plate paint chips but still works great
Works great, but yes the paint on the plate comes off almost immediately. I’ve used it three times and the paint is already chipping. Doesn’t affect the function. There’s a slight “hot” (not burning) smell when you have it on. My coffee stayed warm and my cider did too. Just plug it in and turn it on!

This just WORKS! Keeps warm/hot drinks at PERFECT temp! (but do NOT use as coaster for cold drinks)
I own 3 of these (for different rooms in my house) and they work great! Simple to use (you flip the on/off switch) and it keeps my tea to the PERFECT drinkable (not too hot, not too cool) temperature for me.It doesn’t have the fancy features of some of the other options out there (no auto shut-off, no temp selection) but I recently tried another brand that DID have those features and still much prefer this one. The other one’s coolest temp kept my tea too cold and all the others made it too hot so I kept having to turn it on and off. This one I can just leave on the whole time I’m using it to keep something warm and the temp remains consistent until the drink is almost gone.Other reviews ARE correct regarding the paint scratching off the heating plate…one of my 3 warmers has a LOT of scratching after 8 years of use (the others a little) but it doesn’t affect function, just looks.**I’ve only ever had to replace one of these (just this week) and the issue was caused by a very specific scenario so it’s worth warning others: do not put FROZEN drinks on this device (or anything else wet), even when it is off.**I had set a bottle of water that had been partially frozen on top of it (with the device off) because I’d misplaced my normal coaster and didn’t want the condensation on the outside of the bottle to drip onto my nightstand. I started hearing a sizzling sound, as if the warmer was on, and noticed the red light was glowing despite it being in the “off” position. I assume some of that condensation must have dripped down through the on/off switch and caused a short.The device stopped working after that, and this could be a potential safety hazard. But should be avoidable if you just don’t put ice cold drinks or other wet things on it. I can overlook any of the other cons of this device due to how effectively this keeps my drink at the perfect temp compared to other brands, but I took off one star for this issue because it IS a potential safety issue, even if it is only likely to occur during an unintended use-case (since I could see a lot of people not thinking it would be an issue to use it as a coaster while off).Overall it has worked great and unless I find another one that actually heats to the correct temp (so far I haven’t), this is the brand I’ll keep using, regardless of the cons. Since there’s no point in having extra features if a drink warmer doesn’t actually warm my drink properly. This one does. Will update this review if that ever changes.——**Pros**- It’s straightforward to use. Just an on-off switch.- It’s reliable. I’ve only had to replace one of these 3 I own after 8 years (due to getting water in it).- Doesn’t over-heat the surface it’s on (won’t damage wood) and concerns about mild heating (like if it’s above a desk drawer containing stuff that shouldn’t be heated) can be mitigated by placing it on a tile coaster or something.- The sides of the device don’t get too hot to touch, only the heating plate in the center.- Doesn’t require only flat-bottom mugs.- Doesn’t take up a ton of space compared to some other options while still being big enough for multiple mug sizes (all but my largest/huge mug).- It’s the only one I’ve tried that ACTUALLY keeps my tea the perfect drinkable temperature (warm without burning my tongue). I admit I weighted the pros of this feature heavier in my rating, since regardless of any extra features or other pros and cons, a mug warmer is somewhat pointless if it can’t do this.**Cons**- Paint can scratch off the heating plate but this doesn’t affect function, only looks.- It can make drinks that are almost empty a bit too hot. I turn it off once my mug is at that point.- No auto shut-off or temp control features.- The surface that it’s on does get slightly warm. Not so much that it’s damaged any of the wood surfaces I’ve had it on, but I did notice it melted some Aquaphor in the desk drawer of my nightstand (must have been directly under it) so you may want to place a tile coaster under it if using in this setting.- This device is NOT a good option for someone who wants something that can double as a coaster for an ice cold drink when off (due to the safety risk posed by condensation dripping into the switch), but if you don’t plan to use it for that, it should be fine.

like all the others I see advertised too
OK, I read a number of the reviews posted here before purchasing this mug warmer, and did a little research to check what the power used (wattage) was supposed to be. The manufacturers seem to want to keep this a mystery for some reason — all of them. There were reports that this Mr Coffee device had the same wattage rating as other similar mug warmers that had decent feedback ratings. So, I decided to try it. The power number mentioned was 17 watts, which sounds about right for a device this size. The watts of power generated is THE most important characteristics of any heat producing device and this Mr Coffee mug warmer seems to live up to the purported 17 Watt rating.They don’t put any power or energy information anywhere on the packaging material and there is no information in the small instructions pamphlet either but the bottom off the device says: “120 V 60 Hz 17 W”, so, 17 watts it is.Now, if this electrical device consumes around 17 watts, you can assume some of the heat energy is lost to the table and the edges of the plastic housing and if you put your hands around the device, there is some loss there and my desk beneath does get a little warm. So, clearly 17 watts is not going into the cup. But for such a simply made device, like all the others I see advertised too, it appears to generate a majority of the heat energy at the indented area where the cup will sit.And by the way, the heating are where a mug sits is 3-1/4 inches in diameters — which will accommodate some pretty big mugs.The depressed area where your coffee mug sits gets noticeably warmer than the sides of the device. It is hot but not so hot I can’t touch it. I wouldn’t want to hold my fingers there for very long but it’s not like its glowing red. It’s touchable.So, I took it out of the packaging, plugged it in, set a cup of coffee on it, and did a little work — like maybe twenty minutes.The coffee was a bit cold to start, not even cool, and when I picked the mug up a little later the coffee was warm, the mug was warm..The mug warmer doesn’t heat it to a hot coffee temperature but check it’s name — it isn’t supposed to. It “warms” the coffee.As a couple of reviews pointed out, the manufacturers are skirting the boundary of generating enough heat to make it dangerous to be left heating on a desk. You can’t have a relatively small, inexpensive plastic device have a red-hot burner on it, not when it’s intended use is sitting next to my monitor amidst piles of note and maybe near a textbook or two.If you want really hot coffee, clear a space on your desk and get a true hot plate with which you can also fry bacon. Or get a small stand to hold a microwave. After all that, I was quite pleased with how effective it was in “warming” a drink.If you want it to make your coffee hot hot, you will be disappointed. If you want your coffee to stay warm, it does it’s duty.

Si buscas un calentador para taza, por mucho esta es la mejor opción, sobre todo si amas tomar café, té o cualquier bebida caliente en general. Tengo casi año y medio, y puedo confirmar que sigue funcionando a la perfección, mantiene caliente mi bebida usando cualquier taza (de cerámica obvio) con un tamaño promedio. Incluso ya se me ha caído 2 o 3 veces del escritorio (claramente no lo recomiendo jajaja) y ni así dejó de funcionar bien. El cable considero es lo suficientemente largo, mide más de metro y medio. El único detalle es que el recubrimiento en la base se pierde con relativa facilidad conforme a su uso pero no afecta en nada, por el precio es aceptable. EXCELENTE CALENTADOR 😀
