I purchased a Keurig single serving coffee maker for my son for use in his apartment at college. His roommate did not drink coffee. I though it was a good way to have a single service of coffee, hot chocolate, tea, etc. The B60 version was not inexpensive over $130. The unit stopped working after about 3 or 4 months. And that was not even with everyday use. The water pump doesn't always work. I took the unit apart and reassembled it and it worked once. The LCD screen doesn't always work. I descaled it with vinigar per instructions. And it still only works once, then must be emptied, shaken upside down and reset so that it will make one more cup of something. That's no way for a products to function. The manufacturer is not interested in repairing or replacing the item.
