I love this little mug warmer. It comes in handy so much more than I ever thought it would. Especially if I have a busy day ahead, sometimes I can’t even finish my morning coffee. That’s where this comes in because it keeps my coffee warm while I’m working at my desk or anywhere that I have a plug socket. I just plug it in and sit my coffee mug on top and it keeps it warm the entire time until I’ve finished my coffee. Definitely, a must have if you work at a desk or work from home.
