Small is good when your household needs only 6 double-espresso per day. I installed the included shim because I was on finest settings for the espresso. The shim gives an extra 5 steps. The bellows works well. The machine is fairly quiet. The grind consistency is good, in my amateur opinion. So all good! Why not 5 stars? a) No instructions on how to install the shim. Even online I found little about this. Easy when you figure it out. b) Don't rely on the digital settings - use your own timings or a small scale. Solid four stars.
