Verdict

In 2022 it was Lance Hedrick's favourite filter hand grinder 13:44 23:24. His 2024 tier list gave it an A on a separate filter-only scale 7:50. In his April 2025 filter shoot-out it came second to the Pietro 13:07. In February 2026 it was still his steady favourite over the Kingrinder K7 and Millab M01 28:42. Later that month the Femobook A4Z, a motorised grinder with a ZP6-derived burr, beat it in his blind tasting 0:00.
