The Hamilton Beach flexbrew universal expresso machine came very well packaged,  and the instructions was easy to understand and read. I was so amazed by how easy it was to use, within a few minutes I had the perfect cup of coffee.  I can either make a cup of expresso or a regular cup of coffee.  All you have to do is put your K cup or expresso capsule in it and push the button.  It has 3 sizes of cups , so practically any size cup would work , whether you want a small cup or large one. The Flexbrew is my go too every morning before I start my day , and within a minute I have my perfect cup of coffee.
