I've had several different Keurig models over the years, and the K-Express is my favorite. After 8 months of use I did the 2nd de-scaling, and at the completion, the K-Express would not draw water for brewing, After going through all of the trouble-shooting steps, I contacted support and was sent a replacement. Very easy process.
Ok I basically like this unit but there is one issue that is a real pain everyday I use this coffee maker, so I am going to give this a harsh rating to make my point. According to the manual, there is supposed to be a way to set STRONG BREW MODE as the default, but IT DOES NOT WORK. I tried everything imaginable and even called support and they too gave up frustrated and just sent me another unit under warranty. Guess what? The new unit has the exact same problem. Evidently there is some defect in the software that does not allow you to set this default. Very disappointing because every morning I have to needlessly press the STRONG button. This is just plain bad product design or quality assurance.
Easy to use. I love the variety of options that I have for my morning coffee. My keurig express is so easy to use and more importantly easy to clean. When my last one malfunctioned It was replaced quickly. The 3 sizes to choose from and strong option are fantastic. It's compact and light weight for easy moving around as well. I have no regrets buying it.
