A mechanical tank with commercial-grade 50mm flat burrs and a track record of owners grinding daily for 15, 20, even 28 years without a hiccup. The stepped adjustment makes dialing in a slow, fussy process, it clumps enough to need a WDT tool, and switching beans or brew methods turns into a cleanup project. If you want one grinder for one setup and prize longevity over convenience, the Rocky earns its reputation. If you rotate beans, chase workflow speed, or need stepless precision, you'll outgrow it fast.
