Review on ☕ Coffee Mug Warmer: Electric Gravity Smart Cup Warmer Pad with Auto Shut On/Off for Desk by Peter Sullivan

My Mr Coffee warmer died after 4 years so I started buying. This one heats up well and definitely keeps my coffee hot, after all that's its purpose. I don't like that it only works with a regular coffee mug and not one like my favorite that is shaped like a large teacup. The more the surface is in contact, the warmer, the better it works. I also don't like that it's smooth, with no burr on the edge. I think it's about security. Yes, and the pressure sensor on/off is ok, but I would turn it off and on again myself.
