Review on ☕️ Fashome Coffee Mug Warmer: Electric Cup Heater with Smart Temperature Settings for Coffee, Tea, and Milk - Automatic Shut Off, Ideal for Office Use (Blue) by Amy Mears

This coffee warmer is made of plastic and covered with imitation leather. The USB-A cable is firmly plugged in, but is more than adequate for most needs. It's easy to use, just plug it in and turn it on. There is a power indicator. I hooked it up to my 27" iMac. It works great but the iMac says it's using too much power. I just dismiss the message and it works fine on the iMac. Being hot. It's just comfortably warm, isn't it cool at room temperature.If you spill coffee on it, you can simply wipe it off with a damp cloth.All in all, a convenient way to keep your coffee warm.
