FINALLY able to enjoy my morning coffee without reheating!!!!
Color: Black
Since this mug warmer arrived, I have finally been able to enjoy a relaxing cup of morning coffee. Value and quality are on point. This warmer keeps my coffee warm to the last drop. The cord is long enough to reach an outlet near the end table, easy and simple operation (tap on, tap to lower temp up to two times then final tap off). Auto shut off after 4 hours which I have not used yet as I always unplug my unit after each use, however it is nice to know that is an option. Just one suggestion, Using a mug lid with unit also helps keep the hot beverage at a consistant temp. I LOVE IT and wish I ordered one sooner.

Perfect
Color: Light Blue
For me this coffee warmer is perfect. The disk sides are just right. High enough for a good fit, but not so high you risk sloshing your beverage. The color (blue) is exactly as displayed. Works great and a very good price.

Works only moderately well to keep coffee hot
Color: Light Blue
Not quite what I expected. Although the base heats up as described, it does not keep my coffee as warm as I would expect at the highest temperature.
