I decided to tweak my 3+ year old Mazzer Mini E type B (bought new ) by replacing the original burrs with Super Jolly 33M burrs. To my surprise the originals had the exact same configuration as the Super Jolly. Any thoughts? Factory assembly error? This grinder has performed flawlessly and has exceeded my expectations with minimal clumping, ease of use, cleanup while single dosing multiple blends daily. I got the upgrade itch and thought I'd start slowly before considering the next leap to a titan grinder.
