Burned my finger on the screw

Also, DO NOT touch or try to move the device because the entire unit gets VERY hot and could burn your fingers

I burned my finger trying to look at it for you!!

The old off/on switch was a slider type and was difficult to push, often burning my fingers on the hot plate part as it was right on the edge of the warmer

Keeps my coffee warm enough for me to enjoy (135-138 F) but without ever going over 140 F which increases ones change of getting esophageal cancer.

warmer - -I have fairly LARGE coffee mugs - -

It keeps my coffee hot & I like that the light lets me know if it is on or off (for safety).

With this combination it works well, not quite as hot as I like, but close enough

I like my drink HOT and with this cup warmer, if I put a hot cup on the warmer, it stays hot until the cup is empty.
