Query: Disappointing

Product worked well for approximately six weeks; then it stopped working and I can't find a place on the Amazon site to get customer service. Will probably buy another from my local Bed, Bath and Beyond and think long and hard before buying another appliance from Amazon.UPDATE: Called Keurig Customer Service--they were great and will ship a new unit. Hope this one lasts.
