BurrsManual stainless-steel conical

Adjustment100 clicks per rotation; 8 microns per click

Best fitMaximum espresso adjustment per pound without an electric motor

Multi-factor Index ratings

Six evidence bands that reveal the intended job.

Espresso and filter are assessed separately so an excellent specialist is not punished for refusing the wrong job. Bands use published adjustment, dosing, size, price and evidence—not a claimed taste test.

Updated 2026-08-03 · editorial fit ratings, not owner stars or laboratory measurements

Espresso fitStrong

Brew-range claim and adjustment resolution; not a measured taste score.

Filter fitLimited

Published brew range, burr format and whether filter is the primary design job.

Dosing workflowMixed

Single-dose, timed, auto-stop and direct-to-portafilter convenience.

Counter fitVery strong

Calculated from the published 5.5cm body × 18.5cm handle footprint.

Value contextLimited

Capped because a stable UK price was not verified.

Evidence confidenceMixed

Confidence in exact model, UK price, plug, dimensions and manufacturer documentation.

How to read this: these are deliberately broad specification-led bands, not laboratory scores. A machine can be strong for control and limited for speed—or very strong for filter and intentionally limited for espresso.

Index verdict

What the published evidence suggests.

Adjustment geometry is manufacturer-published. Grinding effort, speed and cup performance vary with bean and user.
