It's the little things in life that make ALL the difference...
I had a very nice Christmas (thanks for asking!), and I got lots of nice gifts. But the best gift of all that I received was the smallest item of them all. Mr Coffee Mug Warmer, take a bow... Truly, this mug warmer* really has changed the quality of my life significantly over the last few weeks. Now, you might read that statement and think, 'wow, your life must really suck for it to be possible for a mug warmer to make it better'. But no, my life doesn't suck. I just really, really like hot tea. You see, I work at home. And I don't have any work colleagues to shoot the s*** with - so, to keep me on my toes, I use caffeine. Lots and lots of caffeine. But, much as I like caffeine (delivered through the medium of tea and, of course, it's more sultry sister, coffee), I get very sad when it goes cold. Indeed, taking a swig of cold tea or coffee is about as pleasant an experience as, say, getting smacked in the face with a wet pair of underpants (we've all been there, right?) Anyway, so I got this mug warmer and I switched it on and, lo and behold, there are no more such unpleasant moments in my life anymore (until someone turns up with a pair of wet underpants anyway). One of the small but incredibly irritating daily occurrences that I had come to think was inescapable has now been resolved! (Yes, things can actually get better!) So now, when I am distracted by a Skype call or any other task and so have to abandon my tea for 20 or 30 minutes, I can now confidently return to it knowing that it will still be piping hot (or very warm at least) and utterly satisfying. In other words, this mug warmer product delivers the goods and then some. The tyranny of cold tea has been defeated. And the misery of having to trudge downstairs to heat it back up in the microwave is no more. (Heck, at this rate I might never need to move from my office chair again - progress, eh?) But seriously, if you want a cheap mug warmer that keeps your drink at approximately the same temperature as you prepared it at, then this warmer will do the job nicely. I leave it on all day (yes, us home workers are total rebels, didn't you know?) and it has paid for itself many, many times over by now. *One thing that I have to say is that, while brilliant, this product is NOT a 'warmer' - i.e. it does not *warm* your drink up at all. Rather, it *maintains* your drink at approximately the same temperature as you prepared it at and for a good length of time. For example, if I prepare a cup of tea (which I am about to go an do, by the way), and put it on the warmer, it'll keep it at the same temperature - with only a very slight loss of heat - for up to an hour and beyond. As a voracious tea drinker, I've never actually let a mug linger long enough to see if there is indeed a point at which it will lose all heat. So surely that's a good sign, no? Bottom line: how can you call yourself a serious fan of hot drinks and not own this product? Shame on you! SHAME! Update (2 weeks later): bonus feature detected! If you are like me in that you tend to spill drinks and in the process your mug tends to drip with coffee a lot, you are going to love this... This mini hot plate warmer will sizzle all drippage away instantly once you place your mug down on it, meaning that you can also avoid any future coffee stains on your table. Then all you need do is wipe the warmer clean once it is turned off / cooled down (unless of course you're like me and you don't care). Score!

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.

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.

True tips and use for SOUPS and preparing lunch
Mr. Coffee mug warmer: As I use it, I will update this review. Cord is long (3.5 feet), the actual heating surface is 3 and 3/8 inches diameter, and it's well made and inexpensive. It turns on with a red light on the unit (unlike another brand that has the on/off switch on the AC electric cable). A superb substitute for schlepping my soups in with a thermos every day (hard to clean, extra work at home, etc.) My goal: warm soup at my desk. I don't want an open flame (e.g. alcohol cook stove), or a very hot 750+ watt cooking element/hot plate. A small Crock pot is hard to eat from and wash--so, I thought this Mr. coffee might be what I want. I don't drink coffee, but could see using it for hot cocoa. The test: I can put a room-temperature full 8 ounce Campbell's Soup--chicken noodle, to be exact--contents in an enamel-coated aluminum 12 ounce cup with lid, and in 30 minutes it's fairly heated and I could eat it, but in one hour, it's nice and toasty and ready to eat. It's hot enough that I cannot touch the bottom of the cup. I was concerned about the honest reviews that said this does not get hot enuogh--but after using daily for a week, it's mighty hot. I certainly cannot touch the warmer surface--it's far too hot. My office is not near a microwave, and this is a lifesaver for me. I may try canned stews next. I adore eating at my desk. A fellow office mate actually warms water--not to boiling, but very hot--over and hour and then dumps it from the cups into camping meal bags (cook in bag types, like Mountain house) and eats well every day. Sure, if someone had a microwave it's faster, but why challenge the entire office for microwave time in the grody kitchen room when you can set this out an 11AM and be eating well by noon. Here's the exact cup I use, which fits the Mr Coffee well. Coleman 12 Ounce Enamelware Coffee Mug (Blue) Tips: The cup makes a big difference. I use an enamel Coleman aluminum cup, which holds one soup can well (not too close to the top), and conducts heat exquisitely. I have no clue is a hard and thick ceramic coffee mug would work. Also, I put a lid on the cup to hold heat, and so I don't get paperclips and junk in there while it "cooks". Lids reduce heating time by 18% (according to camping websites). I use a simple ceramic drink coaster that I had at home for my lid--any nonflammable lid would work. The lid helps. Also, the Coleman mug that I use is flat bottomed, thus using the entire heating element successfully. A curved bottom mug may not heat as well. P.S> Okay, I just did Campbell's Vegetable Beef soup in it today, thick and I added no water, and it took about 1.5 hours to get fully hot. Still worked great, but clearly the thicker the soup, the longer the heating time. Also, the heating is most intense at the bottom of the mug or cup, so (1) stirring helps, and (2) a tall style ceramic mug or cup would not be as good as a squat one. I bought a second one for home since I liked the first one so very much, and to test if the first one was a fluke and just extra hot or something. Guess what, no fluke. The first and second are equally as hot. Postcript: just for kicks, I put tap water at room temperature in the blue Coleman cup for 60 minutes on the Mr Coffee warmer, and I couldn't even stick my finger in it at all. It was hot! Not boiling, for sure, but clearly hot. I wouldn't want it that hot to drink or to eat. And, so, I added an ice tea bag and took it off the Mr Coffee and drank tea. PLenty hot! Lovely! Bon appetite!

Acceptable for price point
The product works fine. I have had it for several years now. It keeps my beverages warm without scalding them. If you like your beverage very hot, this is not the product for you. Temperature of this heater is just above luke-warm. Also, the black color wears off on the surface where your cup is placed, and the silver base shows through after daily usage.

Simple solution to cup warmer not heating fast or hot enough for cool, full cup-- now it can, using an old hiking tool & physics
There is a problem cited throughout these reviews that since the mug warmer is not a hot plate, and doesn't reach higher temperatures, it can only help keep a mug warm. It cannot make hot a cup of coffee or tea from a cold start. I wondered about this, and tried it out, and yes, it is a problem. But there is a simple solution, cost about 10 cents, using a solution from physics and proven on long hikes. I tried it, and it works better than expected here as well. I can take a cup of water from a cold start to being just the right temperature for sipping, not quite steaming, but hot! Here's the physics: there are several types of heat, the most important in this case being radiant heat. Radiant heat is called radiant heat because it travels in rays. In this case, it comes up from the surface of the warmer, and yes, there is some other types of warming going on, but most of what seems to be happening to the liquid is that the radiant heat is traveling through it, and then dissipating into space. The cup loses other forms of heat too, but by just solving the radiant heat loss problem, you will have solved the entire problem of your warmer not being able to warm full cups of coffee or tea, or make cool water warm to start with for dissolving the tea or coffee in it. (I even use loose tea with this solution, and it works fine; it gets hot enough that it does not have to be a mix.) So what do you do to overcome radiant heat loss? A burner would just apply more heat. But if you wanted a hot stove in your office you'd buy a burner, for about 5x the cost of this, and then run the risk of injury in tight quarters. In this case, apply a radiant barrier. A radiant barrier can be fancy or expensive, but you can fashion a very serviceable and even decent looking one with practice out of about a foot of aluminum foil. Anyone who has been camping or tried to travel light while distance hiking knows that you can make a light pot cozy of aluminum foil that serves as a shield against win. The surprising thing is that this simple material we are used to using for wrapping pot roast has the amazing property as applied of cutting your need for fuel dramatically on the way to boiling water. So applied to the mug warmer, fill your mug, put it on, then by folding the aluminum foil a few times to a) stiffen it up, and b) fit around the cup, make a loose fitting wrap that sits just outside the mug, not too tight since you want to re-use it many times. Then apply a paperclip, preferably a small binder clip to joining the foil. Of course you can use other things as well. This way it lifts right off, and can be put right down. Of course, just going around the outside of the mug, the most important area is left open. So fold and refold a second piece of aluminum foil into a stiff square that rests on top of the lip of your mug. Actually this part alone is often sufficient to keep your coffee far hotter than the burner alone, and will work to heat up cool coffee. The additional loose wrap around part just makes it that more efficient. This really worked well for me, to the point I am very pleased, and don't have to run down to the microwave to re-heat my coffee or tea, but can do it from scratch, right on the cup warmer. I like the truly functional aspect of it, that I made it myself for ten cents, and can show a little creativity in sculpting it into something that looks alright, plus it recalls some good hikes . . . But if this is too man cave for you, there are pot cozies you can buy on amazon. Just make sure that they have a radiant barrier in them, or put some foil inside them too, tho no one will see it. That way, you keep recapturing radiant heat, and this is probably 90% of the battle. This way, by turning the radiant heat back on the cup, and back again, again and again, you multiply its effect pretty dramatically. IF this proves helpful, or you think it may, please give it the thumbs up. I'd like to see it rise as a helpful review so it can help solve what so many people have complained of.

I really liked this product....Before it BROKE!
This product lasted only a mere three months. Grrrrr!!!! It worked nicely at first but has now conked out. I am very disappointed. Of course Amazon won't accept a return after a month (which is a silly policy and a real pain in the tukus), but I am going to seek out Mr. Coffee and ask for a refund based on the warranty. FIRST, what happened to create negative review: The warmer was working fine. However, I noticed the unit making a very weird electrical buzzing sound; a very unsettling sound that made me instantly squirrely. I checked it and the unit was plugged in but was not turned on. I thought maybe some internal wiring was a bit loose or it was dirty. I unplugged the unit and the buzzing instantly stopped. I cleaned it carefully and plugged the unit back in. The buzzing started right back up again. The sound is very familiar to most of us...that disconcerting buzzing sound that makes you feel like something is about to catch fire due to bad wiring. I double and triple checked to make sure the unit was not turned on, and this made me even more nervous. i tried leaving the unit unplugged for a few days then try again. Same result. Now it is just a piece of junk I don't think I can even recycle. SECOND, product review before failure: As other reviews have mentioned, this will keep maintain the temperature of liquids that are already hot. It won't heat up liquids that are lukewarm. For any coffee warmer, you have to make sure that your cup is sitting directly on the warming plat. If your cup has a small stem or stand, it won't maintain the temp. of the liquid. Thick walls or base of your cup will diminish the warming capability, but not really by that much, I actually found a very unique use for this as well. I like candles very much. When you light candles in jars or glass containers, there is always a small amount of wax that doesn't burn before the wick goes out. I want all the smell-good from the candle! So, I put the jar on the coffee warmer and it warmed the glass enough to melt to leftover candle wax. It was a nice way to enjoy the aroma of the candle and finish off the rest of that wax in the bottom of the jar. Another brand of warmer will do the same thing for me. The very few benefits of this product are certainly not worth the risk of the price and the freaky electrical failure I experienced. I am going to seek out another option and, based on my experience, I would suggest you think about doing the same. Take care and happy shopping!

Not Pretty, But Pretty Great!
I work from home and keeping a warm cup of bliss is a must. I ordered this back in 2014 and three years later it is still a worthy purchase and one that has made life a little bit sweeter. BASICS So it's not the prettiest thing ever. Black, kinda shiny plastic with a cord that is about 65 inches. On/Off switch is pretty basic and while the indicator light isn't that bright and I can't always tell if it's on or off (what's the point then), it is easy to see as it is located on the top. WHAT FITS ON IT I measure the "seat" for mugs to be about 3 3/8". Yes, it fits Starbucks "You Are Here" Collectors mugs. Yes, you can use mugs that DO NOT have a flat bottom and in my experience it heats up great. I have never felt the need for a flat bottom mug or even a cover for my mug to keep the heat in as the warmer does a great job at that. No, it does not easily fit Bath & Body Works 3-Wick Candles, although they can still sit on top of the lip and heat up. I've done this before and despite the space between the candle and the seat of the warmer, the wax will liquify. The only issue with these types of warmers and large candles is that they will heat from the bottom-up, so you will not smell your candle until it is almost completely liquid. By then it's been hours and me-time is over and done. Not to mention that doing so will mean your wicks will have fallen into the hot liquid wax so don't plan on ever using those later! If you're looking for a more practical candle warmer, try one that heats from the top down so you can get your much needed aromatherapy on quickly. I've purchased the Candle Warmers Etc. Aurora Candle Warmer Lamp, Bronze which worked really well and fit the 4" bottom of the 3-Wick Candles, although at the time of writing this it is currently unavailable. HEATING CAPABILITY I have had great experience with the heat from my Mr. Coffee warmer. It literally brings back a cold cup of joe to really warm temperatures. I once left it on all day (lol my bad) with hot cocoa and when I came back it looked as if the liquid had all been baked off and I was left with gross dry cocoa crust. Yum? I also went ahead to do you all a solid and got out my handy dandy EtekCity infrared thermometer gun and did some temperature measuring. After a while of having an empty mug on the heater, the bottom of the mug 145ºF and the warmer's base was 250ºF. I have no idea how that helps but there it is! All I can say is that it does the job of keeping my drinks nice and hot. :) COMPARISON The only warmer I have to compare this to is HEYANG Electric Coffee Mug Warmer and Beverage Warmer Waterproof Glass Panel Electric Heater Plate with 63 Inches Long Cord Great for Office Home . Great listing name. I got this as a Christmas gift this last year because I wanted a mug warmer that looked pretty enough to be out in the open like in the living room where people will see it. On/Off indicator light is on the side, which is okay I guess. (God forbid if I have to lean over a little to see if it's On.) Loved that it was completely flat and had no lip, but reviews said it was best used with flat bottom mugs. WHO HAS FLAT BOTTOM MUGS? I thought maybe they were just being picky. After all, people say that about Mr. Coffee but I totally disagree as it heats all my mugs just fine. But unfortunately I have to agree with the reviews for "HEYANG Electric Coffee Mug Warmer and Beverage Warmer Waterproof Glass Panel Electric Heater Plate with 63 Inches Long Cord Great for Office Home" and say that it's heating capability for my standard non-flat-bottom mugs isn't that great and I'm a little disappointed. If you find a pretty one that works like Mr. Coffee does, please tell me in a comment!

Compré hace año y medio. En definitiva un excelente calentador para taza.
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 :D

Best coffee warmer and works very well
Best coffee warmer and works very well. Have been using it for over a year now and still works perfect. The Plate does get very hot so you wouldn't want to touch it. It sits on my desk at the office and keeps ceramic cup very warm. I find if you place something to cover your mug the liquid gets much hotter. Keep in mind only works with ceramic mugs. Although it does not have any auto shut off function, I simply place it on a timer that turns on automatically and shuts off at a specified time. This ensure's it does go off at the end of my shift. Wouldn't want to leave it on accidentally over a weekend or so. There is a little light indicator but the mug is usually covering it. Highly recommened to keep tea's, coffees, warm beverages hot-warm.
