I had a Keurig that was less than 6 months old and deemed to be defected. They very promptly replaced it with no problem. Great company that stands behind their products.
Unfortunately this is the 3rd machine I have received in less than 2 years. The first one lasted less than a year, but was quickly replaced under warranty. The second one lasted less than 6 months, and was also replaced quickly. I am hoping this 3rd one lasts a lot longer. The replacement process has been very good, but not sure I would buy another one. I owned one of the earliest models of Keurig and it lasted for more than 10 years. So something significant has changed
The Keurig Team preformed excellent service and accommodation in shipping a new Coffee Maker because my coffee maker that was only a couple months old quit working for no reason. They quickly replaced it and were delightful to work with on the phone!
