LOVE IT!! No more lukewarm coffee!!
Color: Black
I have a glass coffee mug with a slight ridge on the bottom so I wasn't sure if this would work with my mug.
It did wonderfully! I found that the lower temp. is too low for how hot I like my coffee, but the next one was a bit too high,
HOWEVER, it was drinkable I just have to blow on it a little. But, even if I forget, it's NOT TOO hot to where it hurts.
It's VERY easy to use, and I'm old, hahaha

Keeps my coffee to temperature
Color: Black
it works great at keeping your hot drinks hot, unfortunately you have to remember to turn off once you are needing to step away or leave for the day as it will not turn off on its own until about 8 hours later, drying the coffee or drink and leaving a dry paste in bottom of cup.

it keeps my tea hot for as long as I want it
Color: Black
I really like the cute design of this mug warmer. I bought two so my husband and I can use them at the same time. My larger mugs fit perfectly on it. The four temperature settings, timer, and auto shut-off feature are all very useful. Now I can take my time and truly enjoy my tea.

Love them as a cheap, effective warmer.
Color: Lavender
These really work well and are inexpensive ($20). I bought one for myself and my wife.
Up front they tell you what kind of mugs/cups not to use, so read the information areas. We tried insulated mugs and the heat doesn't get passed the insulation barrier and the outsides get pretty hot to touch.
We now use ceramic mugs and they work very well on these warmers.
There are a number of temperature settings and we found the higher settings to be too hot. You will have to experiment with your own mugs to see what works.
The sensor works well letting the warmer know if a mug is in place and it will shut down after 5 minutes without a mug. Unless your cat comes along early it won't get its feet scorched accidentally.
The automatic timer works as advertised as well.
Four stars because I found that trying to figure out how to actually turn the warmer off was a bit difficult and not so intuitive.
Would definitely recommend these warmers. Hope this review helped.

A very good present for someone special
Color: Black
I got this from a girl you can go ahead and melt scented candles. Just stick the holder down on. It puts out a nice scent cause you 12 hours of warmth to maintain your cup of drink or sent up the room a bit works well.
