I bought the K-Supreme and am now on my third coffee maker. When it works it is great, however, after a few months it stops working. I will say that the support staff at Keurig are excellent. They sent me out a replacement coffeemaker immediately each time.
I was very happy with the purchase of my Keurig K Supreme plus. After approximately three months of usage the D scaling light started to blink, I followed the de-scaling instructions thoroughly. Halfway through the process the electronic display shut off and never returned. The coffee maker was no longer functioning in any capacity. After a quick call to customer service, and then asking me to perform a few simple steps they determined that a new replacement unit was warranted. I received that new coffee maker in a timely process and it has been working perfectly! We actually on five different Keurig coffee makers in my family and our businesses. We love the product and are extremely satisfied.
I bought the coffee maker two weeks ago but unfortunately it stopped operating after i took it with me overseas. I called the customer support and got it replaced. the coffee maker is excellent with multiple options.
This unit was a replacement for the one that died after only 6 months. I've run vinegar solution thru this new one a couple of times now and the coffee is still tainted with lousy plastic flavor. I regret not going with a K-Classic and falling for the new advanced "multistream" technology hype. Others may have a better experience than what I've got. Perhaps it might improve if I continue descaling and using it.
The process was easy, the call center tech I spoke with couldn’t have been more pleasant! Received the warranty replacement in about a week. Not bad, especially when a letter takes two weeks to deliver right now. Good experience.
