Kingrinder P2

“What a magnificent gallery, so many pics! :) The burr looks just fine. Look at how its machined, the edges are not supposed to be "perfectly straight" or "perfectly sharp". By using the grinder, the edges actually adapt to beans to make less fines in the grinding process later - some people even intentionally do "seasoning" of their grinder burrs, to accelerate that process. The P2 burr is fully capable to produce a good grind for pour over, and other manual brews. The stabilization would probably have been better with a Kingrinder K6 or K2, also the grind speed and overall comfort / UX would be better too, but the P2 is also fine. If there is something wrong with your Switch brews, the reason to fix is likely elsewhere - when using a quality beans, look for brew temps (can be lower with immersion - 85-87°C), water mineralization, and process / method overall, including how fine/coarse you grind.”
