Grind adjustment The sourced adjustment mechanism and any unresolved description conflict. Dial markings are reference positions, not a common scale across grinders. Conflicting stepped and stepless descriptions remain unresolved.	Sources disagree The sources give different answers, so we have not chosen one as fact. Read the attached notes and confirm the current specification before relying on it. The product page says stepless and also mentions 48 settings. The guide describes micro-steps. No single mechanism description is resolved. Sources · 2026-10-20 Fellow: Opus 2 product specifications and standard packageChecked 2026-10-20. We reviewed the official page text on the check date.

Adjustable timed dosing Whether an adjustable grind-duration dose is explicitly documented. A fixed automatic stop is not an adjustable dosing timer. Unknown means the retrieved evidence did not establish this feature.	Not verified We have not verified this value. It is not a confirmed no or zero. Check the original source or ask the manufacturer if it affects your choice. Automatic stopping and a fixed 45-second run are documented; an adjustable dosing timer was not established.

Questions to check before buying	This is Opus 2, not original Opus. Product-page and manual body dimensions conflict, so body fit is not asserted. No controlled sound, taste, grind-distribution or retention measurement is established here.
