My Keurig K-Supreme Plus after about 9 months of brewing great became erratic and unpredictable, at times, maybe filling my cup with a couple tablespoons of brewed coffee. I descaled it, tried different pods but got the same result. I called the warranty department. They asked a few questions and after I took a few pics and supplied the S/N, a replacement was on its way to me. It arrived within 5 business days and is the exact same model and color and it works great. I am most impressed with the process Keurig has in place to keep me a satisfied customer. This is the 4th or 5th Keurig I've owned, and thanks to great customer service, I will continue to be a Keurig advocate.
This process was absolutely simple. I contacted Keurig customer support and they emailed me directions to submit a replacement request: the serial number and a couple pics and it was done. The new machine was received, seriously, within 2 days!
This coffee maker is a replacement for one that did not work right ever. They finally replaced it. Love this one that works! Keurig made it very difficult though to get it replaced.
