Shoddy products, inept customer service.
I have owned three Keurig machines - two purchased, the last one a gift. None of them ever lasted more than two years. The quality of these machines is only matched in poorness by their customer service. My latest product - the K22 single cup - lasted barely 18 months. Just one day it stopped working. I contacted Customer Service who told me they would replace it if I sent them the receipt. Of course I lost it and have no record that I can find of its purchase. That's fine, I'm not blaming them for that. But when I wrote them asking for a little consideration, this being my third failed product from them, they wrote back a generic email that not only rejected my request, but didn't review my information. I gave them my name and address - they wrote me saying "next time provide your name and address." I will never buy a Keurig again and if by some stroke of bad luck I'm gifted one, I will put it in the regift pile for my least favorite person at the office.
