In brief
The 1Zpresso JX-Pro is a hand grinder with 48 mm stainless steel burrs and an external dial on top. It is discontinued. 1Zpresso's JX-Pro page, which now shows the JX-Pro S, says it is out of stock and unavailable. Home Coffee Expert and the Coffee Chronicler both list it as discontinued.
1Zpresso does not name a direct replacement. The Coffee Chronicler says it was "cannibalized by 1Zpresso themselves," first by the J-Max and then the J-Ultra. The Coffee Folk says a JX-Pro S with a foldable handle followed it.
The Coffee Chronicler says it was a popular espresso grinder from about 2020 to 2022. It was built for espresso on a budget. Home Coffee Expert says it "offered incredible value for money." Today it is mostly a used buy.

What it does well
It handles espresso. Home Coffee Expert calls it an "excellent espresso-focused grinder." The Coffee Chronicler says the external adjustment "makes life a little bit easier" when dialing in a shot.
It grinds quickly and evenly. The Coffee Folk credits the large burrs and crank bearings for fast grinding. Once the burrs settle in, it found few boulders or fines.
It is easy to strip and refit. The Coffee Folk says it comes apart without tools and needs no recalibration afterwards. It also praises the silicone grip and wooden knob as "easy to grip and turn."
Where it falls short
It is no longer made, and 1Zpresso's page shows it as unavailable. Honest Coffee Guide warns that parts for older models may be hard to source. Its one-year warranty will not help a used buyer.
Its edges show. Home Coffee Expert says "the grind consistency drops off at the finest and coarsest settings." It adds that these weaknesses stand out more now that newer grinders have improved.
It is big. Home Coffee Expert lists it at 780 g, and The Coffee Folk calls it "pretty substantial" for travel. Home Coffee Expert found it hard to grip for people with smaller hands.
Who should buy it, and who shouldn't
Buy a used JX-Pro if you want espresso from a hand grinder and find one at a good price. Home Coffee Expert says it is "still a great grinder" if you see one cheap. Home Coffee Expert lists a screw-on catch cup, so check the threads on a used unit.
Skip it if you want a warranty, a travel grinder, or spare parts on demand. Skip it too if you mostly brew filter. The Coffee Folk points filter brewers to other 1Zpresso models.
How it compares
The 1Zpresso J-Ultra is 1Zpresso's current espresso hand grinder. Honest Coffee Guide lists 8 microns per click, against 12.5 here, and Home Coffee Expert notes its magnetic catch cup. See 1Zpresso J-Ultra vs 1Zpresso JX-Pro.
The 1Zpresso X-Ultra shares the 12.5-micron click, per Honest Coffee Guide, with smaller 40 mm burrs. It is lighter and still sold. Compare dials in 1Zpresso JX-Pro vs 1Zpresso X-Ultra.
The KINGrinder K6 is a new 48 mm grinder with an external dial at a budget price. See 1Zpresso JX-Pro vs KINGrinder K6. Recipes are often written for the JX-Pro and Comandante, so 1Zpresso JX-Pro vs Comandante C40 MK4 helps too.
Owning it
The Coffee Folk relays 1Zpresso's advice: clean it thoroughly once a month with a dry brush. Do not use water. A damp cloth can lift coffee oils, but parts must dry fully before reassembly. The hand grinder cleaning guide covers the steps.
The Coffee Folk notes new burrs can shed fine dust until seasoned. 1Zpresso still lists JX-Pro S spare parts, without saying they fit the original. It asks buyers to email before ordering them. Before buying used, check the burrs and dial; the burr replacement guide explains what wears.
