Specs
| Type | Hand grinder, 38 mm seven-spoke (Heptagonal) burr with a slower feed for filter and light roasts 1:34 4:07 |

| Microns per step | 25 µm per click 1:34 |

Starting settings
Lance Hedrick keeps one setting for most coffees but doesn't give the number. For decaf he goes two clicks coarser 6:40 39:38. His test unit couldn't get fine enough for espresso 1:34.
| Method | Setting | Context | Confidence | By | Source |
|---|---|---|---|---|---|
| Pour-over | his usual setting (number not given), decaf 2 clicks coarser | 15 g dose. He brews on the coarse side, and the particle spread is fairly tight for a hand grinder, close to a Comandante | approx | Hedrick | 6:40 |
| Pour-over | two clicks coarser than usual | Decaf, because it grinds finer at the same setting and makes more fines | approx | Hedrick | 39:38 |
| Immersion | 80 | 2021 Pentagonal version (China market), clicks. A reader-submitted figure, and the chart treats every setting as approximate | approx | Christensen | grind size chart |
| Pour-over | 60 to 75 | 2021 Pentagonal version (China market), clicks. A reader-submitted figure, and the chart treats every setting as approximate | approx | Christensen | grind size chart |
| AeroPress | 45 | 2021 Pentagonal version (China market), clicks. A reader-submitted figure, and the chart treats every setting as approximate | approx | Christensen | grind size chart |
| Moka | 40 | 2021 Pentagonal version (China market), clicks. A reader-submitted figure, and the chart treats every setting as approximate | approx | Christensen | grind size chart |

Cup profile
- Good for filter, but it loses character if you push past about 22% extraction 1:34.
- Low in fines for a hand grinder 4:08, with a particle spread close to a Comandante 6:40.
- The Heptagonal tastes like the K series. The Pentagonal has bigger gaps, feeds faster and makes more fines, which suits espresso and dark roasts 5:00.
- It may lose a little body with light-roast espresso 4:05.

Weaknesses
Verdict
Lance Hedrick found it hard to beat for filter at about $99 in 2022 1:34 and called it fantastic for the price in 2023 4:05. In his 2024 tier list the Heptagonal got a C (an A on price) and the Pentagonal a D (a B on price) 5:00. In 2025 a Kingrinder P2 came close but stayed just behind his Q2 7:09.
The Coffee Chronicler's take
- 2022: the smallest and cheapest 1Zpresso. The Pentagonal burr suits pour-over but is slow for espresso, taking about 32 to 33 s for 12 g. A China-only Heptagonal version sieved narrower and was the steadiest 1Zpresso he tried 1:31.
- Later units take the X-Pro's Heptagonal burr, which he expects to clean up the cup. It still fits inside an AeroPress and now copes with espresso, for about $100 5:07.
