Review on ☕ MITBAK Innovative Coffee Mug Warmer Bundle: 16-Ounce Ceramic Mug & Lid Included - Keep Beverages Hot for Hours! by Laura Taylor

Let me first say that I am satisfied with the temperature this device keeps my coffee at. This is the main reason I bought it. But it has a thick, heavy cup with a very thin handle that makes it very difficult to hold! I don't use it at all. The device fits in a regular coffee mug, although a closed lid probably won't fit. Second, there are no low, medium, or high settings. This allows you to just click the plus (or minus) button. You have to manually hold the button down to set the desired temperature. Too exhausting.
