Great, but there was a screw on the original adjustment section that seemed to be not required on the new one (would have needed to drill to use it). Not CoffeeHit's fault, but an issue that Baratza should address in their tutorials.
Perfecto y muy rápido, todo positivo
Missing the tiny screw (luckily I still had my old one) and 3 of the parts could have been pre-assembled, otherwise great
Great - but remember it doesn't come with the set-screw or the adjuster knob.
