Review on ☕ Mr Coffee Mug Warmer: Desk Cup Warmer with Auto Shut Off & Touch Screen Switch - Keep Beverages Warm All Day (White) by Heidi Harter

I've only used it a few times but every time I use it starts to smell like burning plastic. I checked the glass top and there is no plastic coating, so I have no idea what's causing the smell. There is also a brown burn mark on the plate. I'm not sure what the problem is, but I will stop using it and will buy another model. A bit disappointing as I was really looking forward to this mug warmer!
