This works great to keep my mug at a perfect drinking temperature (not steaming hot but well above lukewarm).

I find that this warmer works just fine with mugs that have a raised lip around the bottom

This warmer works great to keep your drinks at a comfortable, drinkable temperature

My first warmer stopped working soon after I bought it, then I got this on and IT worked great, then I moved and lost it IN my moved.

It is NOT designed to HEAT UP a cup of COLD coffee, or other liquids and should only be used to KEEP beverages WARM" ; Now that being said, this warmer works just fine

was worried that the warmer wouldn't keep the coffee hotOR - - the hot plate would be too small for my mugs

The entire unit got hot instead of just the burner warmer plate

The outside of the warmer gets almost as hot as the warming plate

Anyway, so apparently this is one, however, that still has some decent wattage, plus it plugs into a regular outlet (not a weenie USB port), has a switch right near the warmer, a light to tell you it's on, and is made of some really premium materials, a hefty ceramic type base and a quality "hot plate" as the warming surface.

The other negative was that the warmer came broken, not thru shipping, but by the screw affixing the ceramic protective plate underneath the unit being over tightened, cracking the plate into 3 pieces around the screw.

This one does not keep my coffee hot enough; it is more like lukewarm.

Not only does it keep my coffee and tea hot, if I let it get cold and then put the mug on the warmer it actually warms it back to hot.

It does get warm underneath the warmer but not dangerously hot.

I don't care much for the weird soap suds looking print, or whatever it was supposed to be lol.. would have preferred it white, or other solid colors even, but that's trivial considering it does what it is supposed to do and does it well

Please don't listen to the negative reviews,,,it does keep your coffee the same from pot to cup.

Keeps your hot liquids at the perfect drinking temperature

Then the deal is close to boiling temperature

As the tea starts to get lower, of course it would be appropriate to remove the cup with little liquid from the warmer to avoid any uncomfortable temperatures

It keeps my coffee hot (drinkable temperature) for HOURS

it will not make cold coffee hot, but it will keep coffee at the perfect drinking temperature if it is fresh

Unit gets hot all over including the bottom which may cause damage to desks.4

The unit itself gets very hot so I keep it on a thick cork

Also, DO NOT touch or try to move the device because the entire unit gets VERY hot and could burn your fingers

Unit gets hot enough to burn you if you touch it by accident for more than a second or two.5

This unit keeps it totally hot so I can linger as long as I like.

They think it is supposed to warm up their cold beverage

First, that it would have difficulty with different sized cup/mugs, Second, the beverage would get burnt at the bottom if left on too long, and Third, how hot the beverage would get, and Fourth, its stability to remain on a surface without moving

(1) Beverage stays VERY warm--no complaints.

When I am drinking a hot beverage, I like it HOT, not warm and at work it is difficult to drink even 1/2 cup of tea before it cools down.

It keeps my tea pleasantly hot, and it is powerful enough that it will warm a beverage that has cooled off.

Now, if your coffee is already cold/warm like it will NOT heat it up

At first it was a powerful little coffee mug warmer that would keep my already hot coffee just right at temperature.

Works better than any cup warmer that I have ever used.

This is an effective cup warmer and is even quite decorative

I should have just gotten a cheaper cup warmer, this one was not worth the extra cost.

It keeps the mug very warm, not hot, but only if you drink it regularly

I've had a cold mug of coffee or tea and warmed it right up with this thing.

Of course, if you have asbestos lips like my mother, who liked her coffee boiling hot, this might not be the mug warmer for you.

The smart mug died after a few months, so I'm going to buy another one of these for use at home.

I was worried based on reviews that it would be too small, wouldn't warm my mug if it had a lip on the bottom like most do, and that it would get too hot for my desktop

As a tea drinker (all day long), this product keeps my cup of tea nice and hot for hours.

It is a great product and in my opinion reasonably priced.

I was worried this would be a cheap plastic product, but no.

I am satisfied and I recommend the product if you like to keep liquids hot for a bit longer.

If they add grips to the bottom of it, this would be the perfect product.

I purchased a Mr. Coffee warmer from Amazon which didn't keep my tea even lukewarm

This cup warmer is just what I needed to keep my tea hot all day

This Norpro keeps my tea and coffee drinkably warm and almost what I would call hot

It will however keep hot coffee or tea fairly hot for a while.

Unfortunately I had to return this cup warmer because it failed to keep my tea hot or warm for any longer than not using it

This thing actually keeps my slightly larger than normal size cup above warm but not overly hot from start to finish as I sip one full hour watching daily morning News

It should have been a small LED, not this cheap thing.

I was gifted this mug warmer by my girlfriend and the nice thing is it will keep your drink warm, but possibly at the expense of your desk

The whole thing gets hot not just the top where the mug goes, so I have to keep it on a ceramic coaster at all times

This gets hot enough on the surface that I don't want to touch it (which is obviously a good thing.)

Keeps my coffee warm enough for me to enjoy (135-138 F) but without ever going over 140 F which increases ones change of getting esophageal cancer.

Now after a year of use it barley keeps coffee lukewarm

All other warmers I've had (about 3 different ones) would only keep my coffee lukewarm

He tried a new one that kept his coffee lukewarm

I was worried this would be a cheap plastic product, but no.

More than luke warm but not quite a hot as when it is first poured.

It keeps my coffee hot & I like that the light lets me know if it is on or off (for safety).

, This is quality made and has weight , its not cheap plastic, and it keeps coffee plenty hot.

but I wanted something that didn’t look like cheap plastic.

It actually keeps the coffee as hot as when I poured it out of the big coffee pot

I thought about knocking off one star for its hideous appearance, but form follows function, or so they say.

No it does not keep the coffee as hot as from coffee pot, but for me that is too hot to drink.

I did subtract one star because the white base does get rather hot

I subtracted one STAR for the hot ceramic base and for not having a auto shut-off

With this combination it works well, not quite as hot as I like, but close enough

But, if your coffee is new and hot, and you place it on there then yes, this keeps it pretty hot for as long as u have it plugged in 😊👍

The main issue is the odor, once it's ON and got heated a bit, a horrible burning odor emits from the item, covering any other smell in the room, it needs to be turned

While I don't personally recommend doing this (and probably voids any warranty), the issue was the very cheaply made switch.

I burned my finger trying to look at it for you!!

Burned my finger on the screw

I like my drink HOT and with this cup warmer, if I put a hot cup on the warmer, it stays hot until the cup is empty.

Keeps coffee hot, as I am a slow drinker on the weekends

I love that it keeps my coffee nice and hot since i'm a super slow drinker

I'm a slow coffee drinker and I got fed up with cold coffee.
