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

I was pleasantly surprised that my unexpectedly favorite cup worked with this item

As long as I do that this product is working very well for me,

This coffee warmer works well and keeps coffee hot

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

This warmer works better than most others because it has a 24 watt heating element.

I bought this 5+ years ago, and its worked really well

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

Awesome works great looks good .

This mug warmer works really well for me

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

This mug warmer works great!

Good looking and works but would like it to get hotter

Great product works wonderfully

That is not how any cup warmers work

The warmer worked great on both large and small mugs (obviously, it might take a little bit longer for larger mugs) and my beverages did not get burnt even if the warmer was on for several hours

Warmer works well
