A great grinder to pair with my flair pro 2. A perfect 10 for both aesthetics and function.

Easy daily use grinder.
Enjoying the ROK Grinder very much, thank you. Grinding my beans every day is simple and easy. Now my husband wants me to get the ROK espresso maker so he can play too. And he doesn’t even drink coffee much.

Exceptional Manual Grinder. Very happy.
Easy to operate manual grinder for espresso & coarser grinds. For espresso I'm using 5 to 7 notches coarser than the finest setting. So, grinds plenty fine. Grind is very uniform and fluffy. First grind or two out of box will be laden with static with grounds sticking to the adjustment wheel and dosing cup (if you're in a very dry / low humidity environment). This will diminish over time. I wet a finger under the tap and use it to stir my beans in the dosing cup (or another cup) until my finger is dry. Then grind. Basically zero static retention. Very happy with this grinder.
