"So simple a caveman can do it" Ok, so maybe Geico has that phrase trademarked, but it certainly applies here. We're talking fast, simple, and savory coffee (as long as you choose your coffee carefully). For those of us who simply do not have time in the morning to make a pot of coffee, this thing is the cat's pajamas. The 3 different cup size selections are a nice feature. Depending on the strength of coffee you desire, you can choose different sizes. I usually hit the larget button and it will just about fill a 12-ounce cup witha little bit of cream. Keurig's customer support department is really great as well. I had a problem with the first machine I bought and they sent me a replacement machine, no questions asked.
