Even when using a cup with a thin bottom the coffee only keeps at a very lukewarm temperature

This warmer keeps my coffee at a drinkably warm temperature for hours

I love this cup warmer, which keeps the coffee at a perfect temperature

Temperature to keep my tea hot is good though not too hot just right.

The temperature is okay, but not quite hot enough for my taste.

the return window closed, it's not even worth the cheap price.

Never have to use the microwave to keep my coffee drinkable and the price is a total bargain from all those I looked at

the quality of this i e is extremely poor.

However, he consistently annoys my mom and I to reheat his chai

Good price, but it does not keep your beverage very warm

I got the black warmer with the black hot plate and the first time I set a mug on it the black paint scratched off the hot plate

They should just leave the hot plate as is, not painted in black

The black paint started peeling off the hot plate portion of the unit after the first use

black paint came off the hot plate first time used, but no

Either I have a defective warmer or Mr. Cofffee doesn't understand the importance of a "HOT cup of coffee"

This is a great warmer that keeps my coffee hot the way I like it

For $11 it keeps my coffee warm much longer than if I didn’t use a warmer at all (aka cold in 3 minutes).The main drawback for me is the size

I have bought more expensive coffee warmer earlier, which was great

Either way, this thing is great especially if you are working from home and don't enjoy drinking your hot drinks cold

This works great to keep my coffee warm while I'm working

The warmer works as advertised, but only keeps my cup of coffee mildly warm

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

It was super cheap compared to other models and works perfectly.

I tend to slowly drink my coffee and this definitely keeps my drinks warm

; that is to say, it can keep the drink at similar temperature but not to warm it up

I'm the type of person that doesn't like to drink cold warm drinks so this is a great purchase for me

You can use it to keep your hot drink warm for longer but it will keep your drink slightly warmer than room temperature, not much

It keeps hot drink warm for longer time but couldn’t warm cold water quickly.

I love the warmer however where the cup sets the “paint” scratches off where the coffee mug sets on it

I love this cup warmer, it keeps my coffee warm, not too hot (perfect for me) throughout the day

If a hot cup of coffee or tea is left on the warmer the liquid will remain warm

If you place a cold cup of coffee on it, it will not heat up your coffee as my wife discovered.

It certainly won't keep a cup of coffee hot, maybe warm enough.

Bought as a gift for my husband because he hates for his tea to get cold (or even luke warm) while he works

It keeps my tea or coffee at a nice, warm temp- not too hot, just right

but I’m a slow drinker and within minutes my tea goes cold

Then it stays hot and in addition to wasting energy, is in fact a safety hazard.

Keeps my coffee almost as hot as when I poured it in down to the end.

The black on the part that heats is easily scratched away by cups an that’s worrisome to me

Can not recommend due to my experience , a safety hazard.

and when i set it on this when i drink it it stays warm and does not taste burnt

Heats up well and does the job but after one use the paint on the plate is all scratched up just from placing and removing cup

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

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

This mug warmer is very effective in keeping coffee hot

With this little nifty thing I can keep my coffee warm and i LOVE IT

It works, however, the only bad thing about this product is that it discolor very fast, since the first use the color (black) already loses its color.

THIS THING IS THE PERFECT THING TO KEEP MY MORNING COFFEE HOT

Only thing is the black heating surface scratches easily and shows a shiny underneath surface.

Another annoying thing is the surface of the heating element scratches when you place a porcelain coffee mug on it.

I have two, my friend has one, and they're all consistently losing the material from the heating pad.

The cord could be longer and the part where you set your mug on is made with poor material and comes off easy

Only used this product once and after that it would not work again

I got this as a gift for my mom and sadly the product is defective and did not work

This product does not really keep your coffee hot but just warm.

works fine, but heat from element eventually cracked the surrounding plastic and finally a piece broke off.

Only things keeping it from a 5 are the build quality (rather cheap plastic that scratches and scuffs easily), and I wish it had a lower profile

I'm disappointed that it doesn't keep my coffee as hot as I like it

Only complaint is the black cup surface scratches easily and silver underneath shows

My only "complaint" is that the black paint on the hot plate itself scratches off very easily, revealing silver beneath

My biggest complaint was that after my 2nd or 3rd cup of coffee in a usual coffee mug the black paint on the heating surface is scratched off so I can see the metal beneath.

While this does keep coffee and tea nicely hot, the coating on the heating plate is not a good quality.

I knew that it wasn't the best quality and since it does keep my coffee from getting cold, I'm not terribly disappointed.

Very disappointed in the Mr. Coffee brand for making poor quality products.

Keeps my coffee almost as hot as when I poured it in down to the end.

The very first use a ceramic mug scratched the black paint off of the heat pad.

The heating pad appears to be painted metal, and the paint begins to scratch off after first use!

I purchased this not for coffee but to warm part A of my crafting epoxy

It keept my coffee lukewarm until the end then it was hotter with less liquid in the cup

This will keep your coffee lukewarm at best and because of that, I plan to return it

BUT, the pretty black coating on the heating surface started flaking away the first time I used it.

the first time I put my mug on it the heating plate collapsed on one side and my mug was at a dangerous slant

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

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.

She says her coffee stays warm the entire time she’s using it and doesn’t have to get up anymore.

I'm a slow coffee drinker so this kept it warm all morning at work or during the work-from-home quarantine

Keeps my coffee warm which is a good think cause I am a slow drinker.

this is not the mug warmer’s fault but yours, dear warm beverage drinker

It is the absolute best gift for the slow coffee drinker in your life

However, the first time I sat a coffee cup on it, the black top coat started to chip

I did notice after the first time or two of using it that the black coating on the heating plate started peeling/breaking off

After one use, the top coating started scratching off already.

I did notice a burning smell the first day I used it, and noticed some of the black paint on the warmer pealed, and small scratches show up daily, so it's not perfect, but it gets the job done

I am not much for smoke in the house, but love nice smelling candles smelling up the entire house

Update.2/22/21.. this warmer lasted about s month and a half

While it works nicely, the one I received had some scratches on the top and there was a burning chemical smell whenever I turned it on

The smell was giving me a headache and my throat felt uncomfortable whenever I used it

This one works on getting warm n staying warm at a steady level

I feel like this is the perfect temperature, any hotter would make your beverage burn your tongue, or scald your hand if you happen to touch it

Does not keep coffee warm and heating plate is already showing o be defective.

This keeps coffee hot enough that I can drink it comfortably without burning my tongue and not too warm that I feel the need to go warm it up in a microwave

I do have a wimpy baby tongue, I don’t like my liquids quite as hot as the average person and this keeps it at a great temp for me
