after a few weeks of careful use it got seized up so it got a tear down and reassembly. seems to be working now. a few random aluminum filings which was weird to find. But it looks Great!
This grinder has been amazing, it has the power to grind through even really light roasts, one small thing would be to have the premium version have a metal catch cup
Much much better than OPUS (1). Auto stop works great, retention is low, maybe even a better tasting coffee [more clarity] due to the bigger burr. Now I have to give away my OPUS to some unsuspecting friend :-) There's one thing: I select the grind size every day a few times and I wonder if the knob system will get loose over time.
