Purchased the Rocky with a Silvia as a package deal. I've been very happy with it, and am thrilled with how quiet it is compared to my other grinder. I would be happier if the doser dropped the coffee square into the PF, but it's a minor detail. It took a little practice to get it dialed in with the Silvia, but once I did that it's been fantastic! You have to check to see where your true 0 point is, but once you know, it's easy to dial up to the correct grind. I've been told that this will change as the burrs wear down, so keep an eye on it. When your pulls start to get a little long, then adjust it a click and test it then.
