| Best for | Enthusiasts who switch beans or brew methods and value a simple low-retention single-dose workflow | Buyers wanting one sub-£200 grinder for espresso and filter coffee, especially when changing beans |
| Main trade-off | 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. | 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. |
