JX Pro Coffee Grinder: The Hand Grinder That Punches Way Above Its Price
I bought the 1Zpresso JX-Pro expecting a decent hand grinder for travel. What I got was a hand grinder that makes better espresso than electric grinders costing twice as much. That is not an exaggeration, and it is the reason the JX-Pro has become one of the most recommended hand grinders in the specialty coffee community.
The 1Zpresso JX-Pro is a manual burr grinder built in Taiwan, priced around $159 to $170. It grinds for everything from Turkish coffee to French press, but its real strength is espresso. If you have been wondering whether a hand grinder can seriously compete with electric options for daily espresso use, the JX-Pro answers that question with a definitive yes. Let me walk you through the details.
Build Quality and Design
The JX-Pro feels like a precision tool the moment you pick it up. The body is milled from a single piece of aluminum alloy, giving it a solid, weighty feel without being uncomfortably heavy. At about 680 grams (1.5 pounds), it sits comfortably in one hand during grinding.
The outer barrel has a textured grip pattern machined directly into the aluminum. No rubber sleeve, no silicone wrap, just metal with enough texture to keep it from slipping in your hand, even when your palms are slightly damp.
The handle is stainless steel with a wooden knob that rotates freely on a bearing. The bearing is a nice touch because it means the knob does not spin in your palm while you turn the handle. Your fingers grip the knob, and the knob stays planted as the handle rotates.
The grind catch cup at the bottom screws on magnetically and holds about 30 to 35 grams of ground coffee. A small silicone band inside the catch cup reduces static and keeps grounds from flying out when you unscrew it.
Every part of the JX-Pro is designed to be disassembled for cleaning. The outer burr, inner burr, axle, bearing, and catch cup all come apart with no tools required. Full disassembly takes about two minutes, and reassembly is equally quick.
The Burrs
The JX-Pro uses 48mm conical steel burrs that 1Zpresso manufactures in-house. These are not generic burrs bought from a supplier. 1Zpresso designs and machines their own burr geometry, and it shows in the grind quality.
At espresso settings, the particle distribution from the JX-Pro is remarkably tight. I have compared it side by side (using a sieve set) against a Eureka Mignon Notte and a Baratza Sette 270, and the JX-Pro holds its own against both. The Sette 270 produces slightly fewer fines at espresso settings, but the difference in the cup is marginal.
For filter grinding (pour-over, drip, French press), the JX-Pro produces a clean, consistent result. The burrs do not generate excessive fines at coarser settings, which is a common weakness with cheaper hand grinders.
The burrs are hardened steel and should last for several years of daily use before needing replacement. 1Zpresso sells replacement burr sets for about $30 to $40 through their website.
Grind Adjustment
This is where the JX-Pro really separates itself from the competition.
The adjustment dial sits just below the handle, and it uses a numbered system with clearly marked clicks. Each full rotation of the adjustment ring moves through 40 clicks, with each click representing approximately 12.5 microns of burr gap change. That is incredibly fine adjustment resolution for a hand grinder.
For context, the Comandante C40 (another popular premium hand grinder at $250 or more) offers roughly 30 microns per click. The JX-Pro gives you more than twice the adjustment precision for $80 to $100 less.
Finding Your Settings
Here are the approximate setting ranges I have dialed in over months of daily use:
| Brew Method | Clicks from Zero |
|---|---|
| Turkish | 5-10 |
| Espresso | 12-20 |
| Aeropress | 24-32 |
| Pour-over (V60) | 30-38 |
| Drip | 36-44 |
| French press | 50-65 |
| Cold brew | 65-80 |
These will vary based on your beans, but they give you a solid starting point. The numbered clicks make it easy to record your settings and return to them precisely. No guessing, no counting rotations. Just dial to the number.
Grinding Speed and Effort
I timed myself grinding 18 grams of medium-roast beans at an espresso setting. It took about 35 to 40 seconds of steady turning. That is fast for a hand grinder. The Comandante C40 takes roughly the same time, while the Timemore C2 takes about 45 to 50 seconds for the same task.
The effort required is moderate. You will feel resistance, especially at finer espresso settings, but it never feels like a workout. Light roasts are harder to grind than dark roasts (they are denser), so expect to put in a bit more effort with a light roast Ethiopian than with a dark roast Colombian.
For filter grinding, the whole process takes about 25 seconds and requires very little effort. The burrs chew through beans quickly at coarser settings.
Will My Arm Get Tired?
For a single dose of espresso or a cup of pour-over, no. Grinding 18 to 25 grams is comfortable. If you are grinding 60 grams for a large Chemex or French press, your forearm will feel it by the end. For large batch grinding, an electric grinder is more practical.
JX-Pro vs. JX-S vs. K-Plus
1Zpresso makes several models, and the naming can be confusing. Here is how the JX-Pro compares to its closest siblings.
JX-Pro vs. JX-S
The JX-S uses a different burr geometry designed specifically for espresso. It has slightly more adjustment resolution in the fine range and produces even fewer fines at espresso settings. If you grind exclusively for espresso, the JX-S is the better pick. If you want a grinder that handles espresso and filter equally well, the JX-Pro is more versatile.
JX-Pro vs. K-Plus
The K-Plus is 1Zpresso's flagship, priced around $300. It uses larger 48mm burrs with a different geometry, an external adjustment dial (easier to access than the JX-Pro's under-the-handle dial), and a magnetic catch cup. The K-Plus produces marginally better grind quality, but the JX-Pro gets you 90% of the way there for roughly half the price.
JX-Pro vs. Comandante C40
The Comandante is the JX-Pro's most direct competitor. Both are premium hand grinders in the $160 to $250 range. The JX-Pro has finer adjustment clicks (12.5 vs. 30 microns), faster grinding speed, and a lower price. The Comandante has a loyal following and a slightly different flavor profile due to its burr geometry, producing what some describe as a "sweeter" cup. Both are excellent. The JX-Pro is the better value.
Who Should Buy the JX-Pro
The JX-Pro makes sense for several types of coffee drinkers.
Espresso beginners who do not want to spend $300 or more on an electric espresso grinder. The JX-Pro produces genuinely good espresso grinds at a price that lets you invest more in your espresso machine.
Travelers and campers who want cafe-quality coffee on the road. The JX-Pro comes with a carrying case, and its all-metal construction survives being tossed in a bag.
Apartment dwellers who cannot run an electric grinder at 6 AM without complaints from neighbors. The JX-Pro produces only a soft grinding sound, nothing close to the noise of even a quiet electric grinder.
Coffee enthusiasts looking for a backup or second grinder. I know several people who use an electric grinder during the week and the JX-Pro on weekends when they want a slower, more intentional coffee ritual.

FAQ
Is the JX-Pro good enough for daily espresso?
Absolutely. I used mine daily for espresso over several months with no complaints about grind quality. The only question is whether you mind the 35 to 40 seconds of hand grinding each morning. If that bothers you, go electric. If you enjoy the process (or value the quiet), the JX-Pro delivers espresso grinds that compete with electric grinders in the $300 to $400 range.
How do I clean the 1Zpresso JX-Pro?
After each use, give the grinder a few shakes with the catch cup removed to clear loose grounds. Once a week, disassemble the burrs and brush them with the included cleaning brush. Blow compressed air through the grinding chamber to remove any stuck particles. Do not use water on the burrs or internal components.
Can the JX-Pro grind for Turkish coffee?
Yes. At its finest settings (5 to 10 clicks), the JX-Pro produces a powder-fine grind suitable for Turkish coffee. Grinding takes longer at these ultra-fine settings (about 60 to 90 seconds for 15 grams), and the effort is noticeably higher, but the result is genuine Turkish-grade fineness.
How long will the JX-Pro last?
With proper care, the body and mechanism should last indefinitely. The burrs are the only wear component, and they handle roughly 500 to 1,000 kilograms of coffee before needing replacement, depending on roast level. At 20 grams per day, that is 7 to 14 years. 1Zpresso sells replacement burrs on their website.
My Take
The 1Zpresso JX-Pro is the best value in the hand grinder market right now. It grinds as well as electric grinders that cost two to three times more, it is built to last a decade, and its adjustment precision gives you real control over your coffee. The only trade-off is that you need to turn a handle for 30 to 40 seconds each morning. For most people, that is not a sacrifice. It is actually a pretty good way to start the day.
