Review on ☕️ Coffee Cup Warmer - Gravity Switch and Home/Desk Use - Keep Your Coffee, Milk, and Tea Warm - Perfect Christmas/Birthday Gift by Christopher Penn

I like to take my time in the morning to enjoy my coffee, but I don't like cold coffee. So I bought a coffee maker. The problem was finding a flat-bottomed coffee mug, which was the only type of mug you could use to keep your coffee hot and your coffee mug warmer. So it was useless. The temperature on the heating pad got high enough, but if you don't have a flat ceramic coffee mug, it just doesn't consume anything to heat the electricity. Very disappointed I found flat glass cups but you can't use glass on a coffee warmer. If anyone is reading this and found a flat ceramic coffee mug please let me know. Many Thanks.
