New to the forum, but been following this thread closely.
Received my Eureka Oro today - here are my first impressions:
Great uniformity for espresso grind
Middling to poor uniformity for courser grinds (inconsistencies starting at V60 and getting progressively worse toward the course end)
Bellows are pointless - even with the hopper closed, more air comes out the side of the hopper than through the grounds chute
Minimal retention (measuring 0.1g without using the bellows)
Reasonably quiet; similar to the Baratza Forte, but a little more shrill
Beautiful fit and finish, aside from the plastic bean hopper
Minimal mess - doesn’t throw chaff or grounds on to the grinder or surrounding bench
Overall, I’m very pleased with this as an espresso grinder. It’s absolutely on par with the Niche, but this is not a brew grinder.
One other point to note - my burrs locked after running a few hundred grams of coffee through. I had to take the top cover off, remove the top burr, blow the unit out and reassemble. It’s been fine since - I’ve put just over a kilo through to make sure that everything’s now okay.
If there’s anything you’d like me to test out or you want to find out, let me know!
