Review on ☕️ Misby Mug Warmer: Advanced Coffee Warmer with 3 Temperature Settings, 12H Timer, Auto Shut Off - Keep Drinks at Optimal Temperature for Hours - White by Brian Micheals

At first I was skeptical trying a mug warmer, but this Misby mug warmer completely dispelled my reservations.This warmer has several settings with a Low, Medium, and High for each of three materials - Glass, Ceramic, and Metal. I used glass cups with this warmer.When I decided to first try this out I had two glasses of hot cocoa (about 16 oz each). I kept one glass on the desk by itself and put the second glass on this warmer at the low setting. After a couple hours I checked on each of them, the one on the desk was room temperature while the glass on the Misby was still quite HOT. For part two of the test I drank the hot cocoa then placed the now room temperature glass on the Misby, setting it to High. After about an hour this second glass was now hot as well and pleasant to drink.So far, I have been very satisfied by the performance of this mug warmer. I have a tendency to slowly nurse my tea, so being able to keep it hot over a long period of time is very nice.There is a built in safety feature where the warmer will turn off the heating element when there isn't a cup on it (turning off completely after several minutes). You can also set a timer to heat for only a certain period of time. These features together make it fairly safe to use.The one concern I have to note is that the underside of the device can be mildly warm as well, so be mindful where you place the device. Even after many hours of continued use I don't think the underside was hot enough to be a danger, but still something to keep in mind.
