Réchaud USB pour tasses (jusqu'à 2,9 po de diamètre) pour le bureau, la maison, le café et le thé

Très déçu le café refroidi très vite

ANOTHER UPDATE! I can't believe that I just received a personal phone call from a Wayfair representative in regards to this item! What incredible customer service! So this item may be a dud, but to Wayfair and its customer service, I give TEN stars out of five! Thank you! UPDATE: I tried plugging the unit in just to see if it works, and it doesn't matter that standard mugs don't fit, because the unit doesn't work anyway. My husband and I tried all three in both of our computers, and none of them heated. I thought I found a bargain! I'll go with the traditional plug-in type of mug warmer for more money. Impossible to find an appropriate mug to fit this warmer. I need to return the three I purchased.

Don’t really get warm. Barely warm to the touch

The place where you place your mug is too small for most of my cups, but more importantly, it doesn't keep my coffee warm. It only heats the bottom (of the cups that fit), but barely even that.
