I got this cute mug cover at my local Asian food store for $3

I own another mug warmer from this company, and it's worked great for years

This mug warmer is exactly a month old and its black lacquer started peeling off right after the first week

Does it warm an extra large mug all the way through evenly

This is a mug warmer, not a hot plate designed to boil your coffee.

I would say this is a good mug warmer, though I wish it were just a bit hotter.

I have several tall and skinny mugs, as well as a few thick and heavy mugs, and it works equally well with them all

It does not heat it up so if you put a cold mug with cold coffee, coffee won't warm up.

This mug warmer does not keep my coffee hot, much less warm

I got this mug warmer and it worked beautifully for a week

I got this mug warmer and it worked beautifully for a week

I imagine many average ceramic mugs will not be perfect on the bottom

I love my mug warmer.

It is simplistic - it doesn't have a pressure plate, or automatic turn off, or specific temperature control - but it definitely is my favorite mug warmer that I have found

I would not recommend this mug warmer.

You put an already cooled off coffee mug on

So far it appears to keep the mug WARM, real warm however the liquid inside the cup.....not so warm

Can't finish that first cup of coffee in the morning without getting interrupted and coming back to a cold mug

I love this little mug

Great mug warmer

I had a mug warmer for years that broke, and wanted a quick

My dad tried various thermal mugs but he prefers his favorite ceramic coffee mug and without using a lid.

I doubt that this mug warmer will still be usable in 30 months.

While in use, your mug will be warm

To TRY and keep my coffee warm/hot, I now have to top my mug with either a small porcelain coaster or a couple of folder paper towels to maintain some heat within

Does make bottom of mugs pretty warm sometimes

There isn’t really a good option for keeping a ceramic mug hot in a cold room, so I guess that this might be a good as any of the other thousand options on the market and this one is relatively cheap.

Without a cover of some sort on top of the cup the liquid just barely stays warm with this mug warmer

Works well enough with my thick, well-made ceramic mug or travel mug, but not cheap, thin mugs

The other is that I love big mugs and some of my mugs don't fit securely on the little hot plate -- so I have to use a standard size mug and get up to make tea more often as I work or game

Some mugs work better than others

Even though this is cheap, it’s best to avoid it and look for something else (perhaps a battery operated self-warming mug etc)

The mug warmer does a good job keeping my coffee hot

Only drawback is the surface where I place the mug already has a few little scratches

Looks like my mugs are scratching it but

Keeps a mug warm

Keeps my mug warm but the coating on the pad is already flaking off and ugly.

The mug has a smooth bottom so don't blame the mug.

Make sure to cover the coffee with a lid, I use a plastic coaster to cover it up and insulted my mug

I can now have my coffee in my favorite mugs AND it stays hot until I'm finished ...which is a wonderful little small thing in these difficult times.

It's a great mug warmer, it keeps my fiance's coffee warm without burning it.

The mug warmer works best on plain tea or black coffee.

The mug warmer works well at keeping my drink hot, but there is only one heat setting

My OLD, old, old coffee warmer DID do it's job just fine and kept my usual porcelain mug nice and hot3

I did a side by side comparison and was really disappointed that it takes a long time for it to warm up and does not keep the liquids in the mug warm compared to the other brand I'm using.

I love this mug warmer, a must-have item for me in my office

Keeps my mug warm but the coating on the pad is already flaking off and ugly.

I love this mug warmer.

I also found it's kind of safety concern if you use tall mugs, especially when the mug is half full, because the lower part is hot and the top part still cold, the mug could break if leave it there for long time.

Does not seem to keep my heavy mugs as warm as I like it

This mug warmer is a strong 4 stars

I love this mug warmer

I love this mug warmer

This mug warmer does a fine job of keeping my coffee warm, but the finish is wearing away on the warming plate itself and looks bad.

Works better with a less dense mug, as you might expect.

The mug warmer keeps the mug and its contents perfect to the taste!

This is a very good mug warmer, as well as good for warming up anything else that fits on the plate

This product would warm the mug and make it so hot you could barely touch

Works well enough with my thick, well-made ceramic mug or travel mug, but not cheap, thin mugs

I'm very happy with my Mr. Coffee Mug Warmer, and highly recommend it to everyone who's looking for a coffee mug warmer

I bought this coffee mug warmer with the intention of it keeping my coffee hot as served but it didn’t come close to warming it up to any extent even between having to wait between patients at work

It doesn't make a noticeable difference with large mugs that are completely full of liquid (the laws of thermodynamics still apply, and water can absorb a lot of heat energy), but smaller mugs or ones that are half-full are kept nice and warm

To be fair, I also don't have any flat bottomed mugs, which might make a difference but given how warm the mugs get anyway, I'm not sure it would make a huge one.

The mug I used was made of stoneware and it works.

The mug warmer heats up quickly and definitely keeps my beverages warmer longer

It does what it’s supposed to do, but I recommend a thin ceramic mug if you want to feel any actual real

So far it appears to keep the mug WARM, real warm however the liquid inside the cup.....not so warm

mug- best mug to use is a stainless steel mug, retains heat the best- use a silicone lid to keep the heat in especially when the mug is full to half-full.- no need of a silicone lid if your mug has only half the coffee/tea- make sure to switch on the warmer when the coffee is hot, leave it on as long as you want to drink hot coffee from the mug- don’t forget to switch it off after use- there might be a burning smell, I smelled it the first couple of times I used the

Full disclosure, I use the mug warmer to heat up spray cans in the garage

Oversize mugs will not fit

It's one of the best mug warmers out there, you just have to be realistic about what you're buying

I would not recommend this mug warmer.

This isn't a fancy mug

This mug warmer is perfect.

I thought maybe the mug would be too hot to the touch to keep the coffee a good temp, but according to her it keeps the coffee and mug at a perfect temp

This mug warmer doesn’t keep coffee warm

It gets the outside of the mug super hot as well, however the liquid inside the mug isn’t effected at all

I love this coffee mug warmer.

Keeps coffee at perfect drinking temperature doesn't fit large mugs but works very well with up to 16 oz mugs

, if you have very loved (damaged/ chipped) mugs like myself, it is easy to scratch the paint off of the hot plate

I really liked this mug warmer.

These thick ceramic mugs are unmatched for retaining heat

The mug is hot but not the drink.

The mug warmer works best on plain tea or black coffee.

Only warms small mugs or small candles

The mug warmer works well at keeping my drink hot, but there is only one heat setting

This is a great mug warmer

It should be strong enough to withstand rough mug bottoms

It takes too long to warm up my porcelain mug.

My mug scratched the paint off down to metal

This and Salton were my go-to cheap mug warmers for years

It takes a really long time for the warmer to warm up, and even longer for it to then warm my coffee mug.

A thing to note is that this mug warmer won't *heat up

It works just fine, I can put my mug of coffee on the warmer and put a simple lid on my cup and the coffee will be fresh and ready to drink for hours

It helps keep your mug warm longer than without it.

Why not give their mug warmer a try

Don't know if I gave it enough time or the right mug...but didn't like it

I LOVE my Mr Coffee mug warmer!!

This mug warmer is simple and serves its purpose

The mug put a scratch into immediately.

This mug warmer is very effective in keeping coffee hot

At first we thought there was a rough spot on one of the mugs, but it's happening even with our perfectly smooth mugs.

i bought a mug warmer off of wish saying it would work and it didn't do anything

The first time I used it, there was black paint/stain on the bottom of my mug from sitting on the mug warmer

Ok, it does not keep coffee as hot as my old Mickey Mouse mug

It definitely warms the cup/mug, but the drink will not stay warm

I love my reasonably priced mug warmer

This mug warmer does not work at all

I was excited to get and use the mug warmer

And, it keeps a full mug of coffee just barely lukewarm.

And you might want to look into investing in a higher-end mug warmer.

My mugs aren't particularly rough on the bottom, but even the mild abrasion of setting one on the surface can scratch the plate, and then the finish starts coming off

Doesn't keep a mug this size very warm, but it gets super hot if you leave a small amount in the bottom

It only holds very small mugs & the paint scratched off the first time I used it

A better option is to use a good insulated mug.

Mr Coffee folks, you have lost me as a customer for all future mug warmers

I've no idea why the mug warmer plate's paint marred so quickly

too!it will not HEAT UP your drink, but will keep at same warm temperature when you first set mug downsimple and effective

I have barely had this mug warmer for a few hours and the coating (Teflon

While this Mr. Coffee mug warmer did keep my coffee warm (but not quite as hot as I would have liked), the quality of the heating surface was terrible.

With this mug warmer I can take my sweet time drinking whatever I want and it

I have since tried two different negative gravity mug warmers (the type that shut off when you life the mug off it), and both had problems

and it's not likeI'm not slamming my mug onto it or deliberately grinding the mug against the surface

Gets the mug super

Need to start daintily placing my mug or glass like a proper tea drinker.

I don’t have weird mugs, they are normal ceramic, unfinished at the bottom

This mug warmer is great

I literally just set my mug on the pad and it scratched.

I love my Mr CoffeeI’m at work 6 days a week and the best thing is the be able to enjoy my coffee or hot tea everyday without rushing my drink to just enjoy
