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

Revainrating 5 out of 5

Works better than promised

I have my old Mr. Coffee on your desk with it. While the description and reviews say that a concave bottom mug won't work, my favorite mug has a concave bottom and keeps my coffee as hot as an old mug warmer. I have it on the highest (red) level - and it's doing a great job. I'm glad I bought it, the design is sleeker and cleaner than the old one.

Pros
  • Looks good
