Review on ☕ Stay Cozy with the Smart Coffee Mug Warmer - Auto Shut Off, 3-Temperature Settings, Waterproof, Electric (Black) by Amanda Adams

I've been trying to replace my old Salton coffee warmer for months now. It pisses me off every time I think I've found it. This warmer keeps my coffee hot enough, turns off automatically after 4 hours and has a nice smooth black finish. I'm glad it doesn't work under gravity, it's just a silly option. The only thing that stands out a bit negatively is the very large size. It's 6 inches in diameter and 1 inch thick (big enough to heat my coffee pot). I hope the larger size keeps it from failing in 3 months or less.
