A good all around coffee grinder but not an exceptionally good grinder for espresso, due to its lack of adjustment points.
Positive Product Points
The Gaggia MDF is a very well designed and built coffee grinder. It does not suffer from static build-up unlike some other cheaper plastic bodied grinders.
Negative Product Points
The real downfall of this grinder is its lack of adjustment points (or steps).
Detailed Commentary
This review is based upon a mid 1980's MDF grinder I purchased on Ebay, so it may not reflect the current production configuration. The Gaggia MDF is a high quality, metal-bodied machine that easily grinds coffee into a consistent size without muss or fuss. It is equipped with flat burrs that are easy to replace. A hefty electric motor is provided to turn these large area burrs at a slower speed than that of my previous grinder, the Saeco MC2002. The MDF is provided with 39 adjustment points. This covers the entire range of possible sizes for grinding coffee but does not have quite the precision needed for those using upscale home espresso machines (i.e. a Gaggia Classic or Rancilio Silvia). The difference between 2 clicks can be quite dramatic when trying to "dial in" the correct grind. During operation the MDF does not "spew" ground coffee over the counter, nor does it wander over the counter like some other lighter grinders. It is quieter during operation than the MC2002. The MDF's doser is adequate for the purpose intended, but I measure my coffee by weight, not volume, for my espresso shots, so the doser is not important to me. If I were buying a new grinder today, at full retail price, I would recommend the Rocky over the MDF, in this price range.
Buying Experience
I purchased my MDF grinder on Ebay and had no problems. Your mileage may vary.
