Yes, I have an update. The static situation has settled down somewhat, but not entirely. I’ve grown to live with it, and picked up a little mini-vacuum to satisfy my need to keep the work area clean. I JUST got the refractometer 2 days ago (delayed), so just at the beginning of my experimentation.
The occasional messiness aside, what I have grown really fond of with the Femobook is the absolute improvement in grind consistency. My shot pulls are extremely consistent, and only need an indexed adjustment as the beans age. I have not had this level of consistency with the NZ. So yes, I’m warming up to the unit for sure.
