I'm addicted, have been for years. I got in a habit sometime ago making a cup in the afternoon, now if I don't have my afternoon coffee I fall asleep.
I just bought one on these, btw...might as well enjoy being an addict, I say.
No filters, just pop in one of the little prepacked containers, hit the "start" button, place a cup under the spout, and you've got freshly brewed coffee. There's dozens of flavors to choose from.
