Query: Convenient and works great for me

This works for me. I have a 4 cup mr coffee that fits perfectly on this unit. I can reheat the coffee when I am ready for the second cup. I did notice that I needed to use a cup that made good contact with the heating part. I use a small heavy duty china cup rather than a ceramic mug and it heats up nicely. I feel spoiled and will likely be buying another one.
