I would have matched my Junior against any flat burr home/ light commercial machine and am confident it would have held its own. The Max is a clear step up from there.
Positive Product Points
Remarkable improvement in my shots. Easy to make very fine adjustments in your grind.
Negative Product Points
Large adjustments in your grind would take some time.
Simply put, this is an extraordinary grinder. Having owned a Cimbali Junior/Cadet for several years, I wondered about the Max and its conical/flat burr mix. Got a used original Max and found it made a notable difference in my shots. I have not replaced my Max' burrs, though I have pulled off the carrier to inspect them up close and personal. While there is no noticeable damage to them, they do not have the razor sharpness of the Junior's, because the Juniors were replaced when I got my machine and I only pull a few shots per day. I do not see any reason to change any of the burrs because of the consistently excellent quality of the shots as is. Besides, the conical ones are supposed to last forever. Fit and functionality is also excellent. Even with the taller hopper that comes on an original Max (unlike the Max/Junior hybrid from Chris' Coffee), it still fits under my upper kitchen cabinets (just barely). I have no problem with the sound or speed, and I find that the "Thwacker" (the doser) works quite well. It is so-named by my three year old son, who operates it daily and who thinks that making coffee with daddy is the very best way to start each day. Sometimes I consider removing the grinds flap that sits in the doser, so that I can sweep any grinds that collect between the burrs and the doser. Haven't done so yet, but thinking about it.
