Brilliant product, extremely well machined, and a joy to hold, use, and look at. Produces a very uniform grind - with an excellent result in the cup. I use it for pour-over - for which it is nothing short of amazing. Of course, I couldn't resist trying some finer grids: (1) Turkish - the grinder produces extremely fine, consistent, and fluffy powder - but be prepared for a VERY long grind time (~4 minutes for 15 grams, dialed to "20" on the grinder. Going any finer than that will exponentially increase grind time with no apparent gain in fineness); (2) Espresso - great grind quality at much more reasonable grind times. Dial-in resolution is quite acceptable (~2 second difference in brew time per click), but if your sole interest is espresso - you may want to consider the JE-Plus which offers better granularity, and comes at the same price range. For my use-case, I believe the K-Plus is the better of the two.
BTW, this is my second order from this store, and the seller provided on both occasions perfect service, timely communication, and fair prices. Highly recommended.
