Overview
The Kingrinder K1 steps up from the K0 with improved bearings and finer adjustment steps in the espresso range. The upgraded internals deliver a smoother grinding feel and slightly better uniformity. The K1 represents excellent value for espresso-curious hand grinder users who want to experiment without significant investment.
