This is our third Baratza grinder in about 20 years and replaces a Virtuoso that finally failed after about 7 years and many thousands of grinds.
Tha Virtuoso was much heavier and had a good build quality, but the ESP has a better set of burrs and more fine adjustments for espresso grinds. It does seem to have a lighter build quality, so time will tell if it is durable.
The ESP dosing cup works surprisingly well, making it easier to get the ground coffee into the portaholder without making a mess.
Service fro Espresso dolce was excellent, but please - no more styrofoam packing peanuts, which pick up a static charge and are a real nuisance to dispose of!
