How they differ in real use
Built from our coffee grinders scoring, each product's published specifications, and verified owner feedback — not hands-on testing.
Both the Fellow Opus 2 Conical Burr Grinder and the 1Zpresso J-Ultra Manual Grinder made our Top 5 Coffee Grinders, at #4 (best value) and #5 (best budget). Fellow discontinued the original Opus on Amazon in favor of the redesigned Opus 2: 48 settings (up from 41), a 100g load bin with dedicated espresso/filter catch cups, and an integrated ionizer that further cuts static and retention. It's new enough that long-term reliability data is still thin, and some colorways ship on backorder from Fellow directly, so we link the retailer carrying current stock. 1Zpresso discontinued the JX-Pro line entirely in 2026 in favor of the J-Ultra, its new manual flagship: titanium-coated 48mm burrs and an external ring with 8-micron clicks (versus the JX-Pro's 12.5-micron top dial) for finer espresso dial-in by hand. No confirmable Amazon listing exists yet, so we link 1Zpresso's own store.
We score coffee grinders on Grind Consistency (40%), Grind Range (25%), Retention (15%), Build Quality (10%) and Value (10%). On that basis the Fellow Opus 2 Conical Burr Grinder totals 8.2 out of 10 and the 1Zpresso J-Ultra Manual Grinder 8. The widest gap is Grind Consistency, where the Fellow Opus 2 Conical Burr Grinder scores 8 against 7 for the 1Zpresso J-Ultra Manual Grinder: particle uniformity. Value also separates them: 8.5 for the 1Zpresso J-Ultra Manual Grinder versus 7.2 for the Fellow Opus 2 Conical Burr Grinder. The 1Zpresso J-Ultra Manual Grinder claws back ground on Build Quality and Retention.
