#9 of 10in Espresso Grinder

91 sources · limited data · updated June 2026

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.

The context that matters

What you're actually buying — and what the data leans toward.

Dataset does not clearly distinguish between Perfetto generations or model years. Discussion appears to span multiple years of the same basic design.

⚠Strong enthusiast community bias toward single-dose workflows and modding. The grinder is designed for hopper use, but most discussion centers on adapting it for single-dosing, which creates workflow friction the manufacturer did not intend.

Common complaints6 issues

▼

−Designed for hopper use but commonly repurposed for single-dosing, leading to 2g retention without modifications

−Stepless dial requires multiple rotations with no clear indicators, making grind setting tracking difficult

−Zero point calibration needed after cleaning or burr adjustments

−Static buildup can cause mess and affect retention

−Not ideal for switching between brew methods or bean types without purging

−Aftermarket modifications often needed to optimize for single-dose workflow
