Bests & Worsts Reviews from Amazon

I have used different brands of a coffee cup warmer over the past 20 years. I like having coffee in a "real" mug at my desk (not some insulated cup), and I like it hot when I drink it. This is WONDERFUL. By far the best one I have owned. This has two settings (not an infinite number between 131 and 176 degrees). 131 Degreees is for those who like their coffee nice and warm, but not too hot. 176 degrees is for those who like it "right out of the pot" hot! I use 176 when the cup is full and 131 if the cup is less than 1/3 full so it doesn't get too hot. I know, crazy to think that "too hot" is an option with a small warmer like this. But it is. But HERE IS THE CATCH, you need to use the right mug. I like discount stores (tuesday morning, odd lots, etc etc. They all have lots of mugs for a couple bucks. Find one with a FLAT SMOOTH BOTTOM. Like a pot for your stove. A typical coffee mug with the raised bottom will not transfer heat any more than a pot on your stove would if the bottom is not flat. Good luck and enjoy.
