This 50mm flat burr grinder delivers excellent espresso and runs quieter than most at its price point, but it's built for hopper-fed workflows, and the enthusiast crowd keeps trying to make it single-dose. Fill the hopper with a week's worth of beans and pull shots from the same roast, and it's a workhorse: consistent grind, solid build, easy to dial in. Try to single-dose and swap beans daily, and you'll fight 2g retention, an unmarked stepless dial that takes three full rotations to move one setting, and a mod wishlist that includes bellows, angled stands, and aftermarket hoppers. Buy it if you stick with one roast at a time and don't mind filling the hopper; skip it if your workflow involves weighing every dose and switching beans constantly.
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.
