Review on ☕ Coffee Warmer Plate – Electric Mug Warmer for Home or Office Desk, Keeps Beverages Warm, 4.5" Diameter (Wood) by Elena Bryant

The heater is made the same as the first unit. I tested several different cups of water, including one made of glass. The highest water temperature was 110 degrees, I was expecting 130 to 140 degrees based on your ad. Your ad can be misleading even if it doesn't list the degree of liquid in the cup. If you know the coffee cup in which the coffee is kept. over 130 degrees on your heating pad I would keep it. Confirm. I am currently waiting for a refund.
