Underrated grinder with an excellent delivery system, but not worth full retail. Must be modified for espresso.
Positive Product Points
Produces a consistent grind with relatively slow speed conical burrs. Does not scorch coffee. Very nice delivery system -- allows grinding straight into a portafilter without the nuisance of stale coffee in a doser. Infinite grind adjustment with a worm gear. Almost the ideal design for a good home grinder
Negative Product Points
Cheap seeming plastic case. Lots of plastic inside as well. Must be modified to grind fine enough for espresso (although modification is easy). Probably not worth the full retail price -- Solis is a cheaper competitor.
The Pavoni PG series gets an undeserved bad rap. These grinders do a very nice job and have an excellent means of delivering ground coffee. Although there is a lot of plastic on the interior, they seem to share the mechanism (including the plastic) with most of the other Italian conical burr grinders. You can pay a lot more for an Italian grinder that is essentially the same machine inside.
However, the full retail price of $160-180 is steep for the quality. At that price, it would make sense to spend a bit more and buy a Rocky or Jolly grinder or a bit less and buy a Solis. If you can get this grinder at a price comparable to the Solis, it's a good buy.
