Review on ☕ Coffee Mug Warmer with Auto Shut-Off for Desk - Smart Temperature Settings, Electric Beverage Tea Water Milk Warmer for All Cups and Mugs - Heating Plate Candle Wax Warmer (Cup Not Included) by Olusola Reid

This is a great little product that works exactly as advertised. I checked the temperature of my coffee outside of the machine and the temperature fluctuated between 131 and 135 degrees. This is the temperature the heater will maintain. It's important to put hot coffee on top straight from the coffee maker as as the description states it retains heat and is NOT designed to bring warm coffee to the desired temperature. I spend a lot of time on video and phone calls. nowadays and it's perfect to sit on your desk. it saves me numerous trips to the microwave. The only reason I give it 4 stars is that in an ideal world it will tell you exactly what temperature it is and give you a few options to choose from. If it were possible, the price would look very different.
