Heavy, solid, and quiet.  Great adjustability on the stepless, a small tweak is all it takes.  The cord comes out the bottom and comes with a normal on/off switch unlike the Mazzer Mini.  The plastic in the doser is thick and solid.  The doser also does a great job of fluffing the grounds and preventing clumping.  Smooth, solid doser lever.

Stepless is not as convenient if you grind for both espresso and drip or french press.  The grinder does get a little messy at times.

This grinder does a great job of grind quality and is easy to adjust, but a small adjustment goes a long way.  Like many people I only grind enough for one drink at a time.  I use a separate timer and 15 seconds is close to a double shot .  I also removed the guard in the doser and use a little brush to clean the grounds.  I also love the thwack, thwack, thwack sound of the doser lever.  Although a doserless model can be less messy and more convenient for single drinks, they also have clumping problems.  I got the black color instead of the aluminum finish and I'm very happy.

I bought it from Chris' Coffee with a La Spaziale Vivaldi II espresso machine.  I could have saved some money buying on sale elsewhere, but I did get an overall discount from Chris' and I know they will be there if I ever have a problem.  They also included their own directions on how to dial in the grinder the first time and it worked like a charm.
