I have to begin by saying this is my first Espresso machine, so I am a rookie trying to learn the art of great coffee.  I love the Barista Pro and the coffee it makes, when I have it dialed in. Since I'm new at making espresso and using a machine, I needed detailed instruction, and unfortunately this is why I am rating it 4 stars.  I have found the manual that came with the Barista Pro to be inadequate in terms of instructions (like how to reset default) and in providing specs for the machine (like what are internal temperatures on the various graphic settings).  As a result, I have spent extra time and grief trying to figure out the machine and dial it in, including phone time with Breville support. User friendly is the term that comes to mind, room for improvement in this area.  Sincerely, Mr Rookie
