Our Verdict
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.
