A great commercial grinder makes a great home grinder as well!
Positive Product Points
Exceptional grind quality.
Very quiet for commercial grinder.
Least messy of any grinder I've used.
Negative Product Points
The auto-grind switch cover makes it difficult to sweep out chute (reduced usability points, but is easily corrected).
At 23" tall it won't fit under most kitchen cabinets (reduced aesthetic and usability points, but this is a common trait of "all" commercial grinders).
Detailed Commentary
I bought a Rosito Bisani & this MD50, to test against my Mazzer Super Jolly. After installing new burrs I tested each for grind size consistency, relative messiness, noise levels, and general ease of use. The MD50 was the best of the three, resulting in me selling the Mazzer SJ & keeping the MD50 as my personal grinder.
The Rancilio MD50 I bought was an AT model - as in "auto-grind". It's designed to keep the doser filled with ground coffee in a busy shop. The biggest down side to this is the micro switch, it's cover, and it's location. The switch assembly is located at the top of the grounds chute, making it next to impossible to sweep out all the grounds. This was solved by removing the switch & its cover (connect the two wires to keep the circuit closed) and plugging the holes with clear silicone sealant.
Unlike the Super Jolly & RR45, the MD50 has a simple rocker switch at the front of the machine (my preferred switch type & location).
Buying Experience
I bought the RR45 & the MD50 on eBay from jp12ee. The items were accurately described and my questions were quickly answered.
