This coffee warmer from BESTINNKITS automatically detects when a weight is placed on it and turns on. This weighted activation is an elegant feature this does not require you to turn it on or off, but it could be dangerous if other objects are accidentally placed on the plate. It has an excellent design to complement the decor of your counter or desk and has a long power cord so it can be easily moved during use. It quickly heats the coffee to the right temperature and if something spills on it, it is relatively easy to clean up. it does not seem to be damaged by continuous use or minor spills. While the actual warming portion of the plate is reasonably small, it can accommodate mugs that are larger than the standard size so they are easy to use with almost any cup of coffee.
