Review on Ingecafea Coffee Mug Warmer for Desk Use - Upgraded Version with 4 Temperature Settings, 4-Hour ☕ Auto Shut Off, Waterproof Design - Ideal Gift for Christmas. Keep Your Coffee, Milk, and Tea Hot! by Farhad Cantu

This coffee warmer will keep my cup warm and that's exactly what I wanted. I never have to turn it over the 2nd heat setting. However, I'd rather have a switch to turn it off than a touch sensor. It wasn't until I started using it on my desktop that I didn't realize how easy it is to accidentally turn it on by lightly touching it with my hand during the workday. It then becomes very hot when unoccupied and there is a risk of burns. Because of this, I've started leaving it disabled when I'm done.
