I've only used a Keurig in my work office, so I was excited but curious about trying the K-Express. 
          As for usability, it has a super simple set up and the process is very intuitive. From a cleaning perspective, it's much less time consuming than a normal coffee pot or larger Keurig. My only caveat would be that it did not come with a self-fill pod so that we could use our own coffee grounds if we wanted.
          Design-wise, it has a small footprint and looks sleek on the counter compared to other bulky coffee makers.
          The price point for what you will receive seems fair as it's simple to use, looks good, and makes tasty coffee quickly and at the correct temperature (not luke warm).
          If you dump your water each time, it's less cleaning and maintenance overall.
