I had my K=Express Single Serve Coffee Maker for 3 months and had a problem with the 3 month clean cycle. After speaking with a knowledgeable service rep on the issue he decided to replace my K-Express with a new one. I would have had the new one in about 7 days but due to shipping issue it took about 2 weeks the receive the new one, no fault of Keurig. I am happily back to my good coffee.
