I was using two already older but pretty good and not cheap hand grinders (Knock Feld 2 and Helor 101). But I recently got the Fellow Ode Gen 2 flat burr grinder ($300) for V60 pour overs at home and it was a complete game changer. At the same time, I took the somewhat recently purchased Fellow Opus conical grinder to the office to use with the Clever Dripper and now my coffee both at home and at the office are substantially better than before.
