My Baratza Encore has been grinding away, day after day, couple pounds a week,)or more, I do the night shift gig at a University ER), and this one has yet to break down in any way. I don't even clean it as religiously as I should.
The grind is consistent and the thing doesn't eat up my entire counter-top.
Shoot, it's not even hideously noisy....which is a bonus for that firstthinginthemorningblearyandmuzzystartoftheday.
I've had grinders that I wanted to hatchet dead because of that harrowing racket!
