Specs
| Dial | The whole barrel twists, clockwise for finer. The locking screw has to be firm or the setting drifts 29:51 |
| Motor | Battery brushless DC, 200 to 1200 rpm. It never stalled, even at 200 29:51 |
Starting settings
No one has shared grind settings for it yet.
Cup profile
- Good coffee, and the stock burrs suit traditional roasts 29:51.
Strengths
- Shaft runout within about 0.05 mm 32:11.
Weaknesses
- An awkward hopper, messy output and over 2 g retained at first 29:51.
Verdict
In 2023 Lance Hedrick said he'd rather have a DF64V, Timemore 064S or Zerno 29:51. He gave it a C in 2024 17:12.
Kyle Rowsell's take
- 2023: a battery-powered 64 mm grinder with Super Jolly burrs, 200 to 1200 rpm and about 40 hours on a charge. It makes thick, textured traditional espresso and passable filter with darker roasts. Grounds fling round the funnel at higher rpm and drop out when you restart, it needs RDT and a stand, and there's no SSP option. $1,150 after its Kickstarter 4:39.
