We enjoy the single cup or pot option. My wife has Irish Tea by the pot and I get freshly ground coffee by the mug. We like that it turns itself off and that there is a programmable start button.
However, this is the second unit we have purchased. The first on lasted about 21 months. The "by the pot" side heater side stopped working as did the program button. The mug side still worked. The convenience of this device is such that we are giving it a second chance.

Pros: Flexible, easy to use and clean.
Cons: Insulated mug not included unlike our first purchase.
