This is my 2nd Keurig coffee maker of this model. ru-vid.comUgkxBrV-RbF5Nk0Rlt9i15aao-YMzqzTG8Vf The first worked fine for more than 2 years, and I could still get a decent cup of coffee out of it if I fiddled with it when I decided to replace it. The problem I had with my first unit was this: When attempting to brew a cup of coffee, the unit would either keep brewing until the coffee was undrinkable or it would not run long enough and the coffee produced was way too strong. I cleaned the unit as best I could but it did not help. So in the end it was just too much trouble to get a good cup of coffee out of it, so I decided to replace it with a new one, which has been working great since I unpacked it.
