No doser, 60mm parallel grinding burrs, heavy duty 285 Watts motor, very good grind consistency.

Adjustment of grind settings is difficult due to lack of markings.  Reportedly timers are not very reliable.  I had no problems so far.  Some coffee remains in the chute after each grinding.

Although it took me six months to select an espresso machine I always knew that Mazzer Mini is the only grinder to buy.  Thanks to Todd Millar from The Original Espresso Machine Company (http://www.espressoonline.com) I learned about Tranquilo.  First of all I liked the idea of doserless grinder in order to have fresh coffee for each shot.  You can compare the specs of Cunill Tranquilo and Mazzer Mini at   http://www.corainc.com/equipment.cfm.  The fact that Tranquilo has larger burrs (60mm vs. 58mm) and more powerful motor (285 Watts vs. 250 Watts) was important to me as well.  Although Mazzer Mini appeared to be a "reigning king” I bought Tranquilo and still think it was the right decision.  The initial adjustment of grind settings was a disaster due to poor design.  Grind settings need to be marked.  Timer adjustment was easier, but not friendly either.  It took me "x" hours and "y" pounds of coffee to set it up right.  Now, more than one year later, I can only smile recalling these first disappointments.  Excellent quality and consistency of grinding conforms perfectly to my Bezzera BZ40.

I bought it in May 2003 from Cora Italian Specialties  (http://www.corainc.com).  Nobody could even match their price ($175), and Paul from the customer service gave me an excellent "comparative analysis" of Tranquilo and Mazzer Mini, which Cora sales as well.
