Certainly quiet, and grind consistency is excellent. I do not experience the mohawk the other reviewer mentions, though I can see how that might happen with the flat spout.
I dinged a star because twice I've had the motor jam. Essentially something happens where some beans get stuck and the motor doesn't have quite enough torque to start. That's fairly startling when you push the button and nothing happens but the countdown timer just goes, and you just dropped a bunch of coin on this grinder. The "solve" of emptying the grinder and then refilling it isn't a treat either. But it's only happened twice in several months, so I thought it merited a single star decrease only.
My two other comparisons are the Baratza Forte and the Mahlkonig E65GBW. This crushes the Baratza for d*mn sure but the Mahkonig is definitely better. That also adds a $k or more so probably not fair.
