Great for drip, works good for espresso, if you have a $3000 espresso machine, maybe a better grinder is a better choice.
Positive Product Points
Grinds my espresso just fine, it does the drip just fine and I have lots of room for improvement if needed either way.
Negative Product Points
Yeah I do get some small balls of grind in the espresso grind, a quick shake and their gone. It is pretty fine powder and pretty oily beans so I would guess it would.
Having had a Capresso Infinity and moved to the Virtuoso. There was a big jump in quality. I have used this unit for about 3 years and in the past 6 month's I have used it for espresso only. Going from drip to espresso wasn't a problem, 6 months after I got this grinder, I took it apart and recalibrated the burrs and got them aligned just right. This was a refurbished unit. I know where it needs to be for drip and for espresso. I know my machine, I know where I want it to work. It does the job right no complaints. those who complain, are just maybe complainers. I do not have a problem with static for 100% of my home roasted beans using a Hottop. I have used fluid bed roasted beans and see it has slight static with those. I can get finer grind if I needed, as I have lots of room for adjustments for espresso grind. Its pretty fine now as it is and I get good shots from a simple Gaggia Expresso machine
