Best for	Buyers wanting one sub-£200 grinder for espresso and filter coffee, especially when changing beans	Buyers wanting a compact flat-burr, single-dose workflow for espresso and filter without moving to a £350-plus grinder	Enthusiasts who switch beans or brew methods and value a simple low-retention single-dose workflow
Main trade-off	This is the original Opus, not the newly announced Opus 2 with 48mm burrs and a stepless side dial. UK Opus 2 availability is still inconsistent, so compare the exact name and burr specification before buying. The original’s hidden inner ring improves espresso granularity but makes adjustments less intuitive than a single external dial. Anti-static performance needs chute cleaning, and Fellow’s low-retention and grind-quality language remains unverified by Home Coffee Index testing. The recorded retailer warranty is 12 months, and delivery cost must be confirmed at checkout.	DF54 is a white-label platform sold under names including Solo, Turin, MiiCoffee and G-Iota; confirm the V4 hardware, UK plug, seller and warranty rather than assuming every DF54 listing is equivalent. Manufacturer and retailer dimensions differ slightly, and the sub-0.1g retention figure is a seller or manufacturer claim—not a Home Coffee Index measurement. Stepless adjustment favours espresso precision but does not provide repeatable numbered clicks. Independent grind distribution, retention, static, noise, speed and durability testing is pending, so no quality ranking is published.	The £559 item price is not the complete delivered cost. The lid needs 43.5cm of vertical clearance when open, and stepless adjustment is excellent for fine control but cannot return to numbered clicks. The manufacturer publishes 72dB during grinding and sub-±0.2g dose consistency from independent test data, but Home Coffee Index has not reproduced those tests. Availability varies by colour and plug, the warranty duration was not verified, and replacement-burr pricing is not yet structured.
