Strengths & weaknesses

1Zpresso JX Pro S
1Zpresso JX Pro S
Strengths
48mm conical burrs are 10mm larger than the Comandante C40 MK4's 38mm
Full-rotation external adjustment ring with 90 clicks per revolution provides precise, repeatable grind settings more intuitive than the C40's relative-click collar
External bearing on the main shaft eliminates wobble found in cheaper manual grinders
Trade-offs
No numbered position reference on the adjustment ring
Grinding 18g for espresso takes approximately 90-120 seconds at fine settings
Stainless steel case shows fingerprints prominently; body finish feels less premium than the C40's anodized aluminum in direct comparison
Niche Zero
Niche Zero
Strengths
100 RPM motor produces virtually no friction heat

Stepless adjustment with magnetically-detented clicks provides micro-level grind changes without the fiddly collar systems of cheaper stepless grinders
Trade-offs
At 100 RPM, grinding 18g for espresso takes approximately 35 seconds

50g hopper holds only one or two doses

Full comparison

The 1Zpresso JX Pro S ($139) features 48mm conical burrs, stepless adjustment, and a 35g hopper. It handles the full range from espresso to french press and is widely regarded as one of the best-value manual grinders available. At its price, it outperforms many grinders costing two to three times more.

The Niche Zero ($629) operates on a motorized 63mm conical burr set at 100 RPM with stepless adjustment. It single-doses from a 50g hopper with near-zero retention — a significant practical advantage for fresh bean rotation and workflow efficiency.

The burr size difference is substantial: 48mm versus 63mm. The Niche's larger burr surface produces more even particle size distribution, which translates to more consistent espresso extraction. The JX Pro S closes this gap impressively for its price but cannot fully match the Niche on technical grind uniformity.

For anyone who can accept manual grinding, the JX Pro S at $139 offers extraordinary value. The Niche Zero at $629 is justified only if daily convenience, motorized speed, and electric workflow matter. The $490 price gap is large enough that most budget-conscious buyers should start with the JX Pro S and upgrade later if needed.
