This is an excellent companion for my Rancilio Silvia (purchased concurrently).  It is relatively quiet, very consistent grind, and I truly believe it enables the user to get the best out of the beans and machine used.  Operation, cleaning and adjustment is simple and straightforward.  For domestic use, this thing is really BUILT.  Big enough to look impressive on your counter, small enough to leave you with some bench space.

Nothing here that should discourage the home user from purchase.  Small nuisances include having to manually clear the spout between grinder and dispenser after each session - fills with grounds, but does not actually clog up; vanes in dispenser do not clear all grounds - I just vaccuum mine every week or so.  Smaller adjustments between clicks would improve results marginally, but only for the OBSESSIVE.

Using the same blend of beans in Rocky, I operate over a one click range, depending on weather, and sometimes roast variations.  Really half a click would be sufficient.  Since new (14 months old), I grind one click finer.  I haven't changed my grind range since the first three months.  

With a properly warmed Silvia, I always get excellent crema, even using two week old beans.  I attribute this mainly to the consistency of the grind achievable with the Rocky.  I have read that there is some improvement in coffee quality with something like a Mazzer Mini, but we're talking a different league (and price range) here.

Minor gripes aside (see section above) the Rocky will never disappoint the home user.

Last one in stock at the time - lucky to get it when I did.
