Overview
The 1Zpresso JX-Pro upgrades the popular JX with finer adjustment steps optimized for espresso. The additional micro-adjustment clicks in the espresso range allow precise dialing that the standard JX cannot achieve. The same excellent 48mm conical burrs and solid build quality carry over, making the JX-Pro one of the best value espresso hand grinders available. For manual espresso machines like the Flair or Robot, the JX-Pro is a natural and popular companion. It grinds effortlessly for espresso with its large burr set, and the resulting shots are remarkably good for the investment. Widely considered the best bang-for-buck hand grinder for espresso enthusiasts.
The 1Zpresso JX-Pro features a 48mm conical burr set, crafted from steel. Grind retention is approximately 0.1g — virtually zero retention, making it excellent for single dosing.
At $159, the 1Zpresso JX-Pro is aimed at home baristas seeking a solid grinder without a premium price tag. Key workflow features include single-dose design (no hopper needed). As a hand grinder, it's completely silent, portable, and gives you a meditative morning ritual.
The 1Zpresso JX-Pro is weighing 0.6 kg, manufactured in Taiwan. Its footprint measures 52 x 52 x 190 mm (W×D×H).

Our Verdict
The 1Zpresso JX-Pro is a hand grinder, which means it trades speed and convenience for portability, silence, and often better value per dollar of grind quality. In the $100–$250 range, hand grinders can match or exceed electric grinders costing twice as much in grind quality. This is the sweet spot for serious home baristas who don't mind the manual effort. If your daily routine involves 1-2 drinks and you enjoy a mindful morning ritual, this is an excellent option. For larger households or back-to-back drinks, consider an electric alternative.
