Quick verdict

The X-Ultra is the lighter 1Zpresso that still covers espresso. It has 12.5-micron external clicks, a 25–30 g capacity and a listed weight of 590 g. CoffeeGeek named it its top versatile manual grinder in 2025. The compromises are a smaller capacity and a dial that is hard to read in dim light.

Buy it if

  • You want one hand grinder for pour-over and espresso that is easy to carry.
  • Single-cup doses of 15–25 g are your norm.

Skip it if

  • You grind 30 g or more at once.
  • You want the finest espresso steps; see the J-Ultra.

What independent testing found

CoffeeGeek's first look found espresso doses of around 18 g took about 45 seconds. It called the X-Ultra capable but "not quite as specialised" as the J-Ultra, and said pour-over grinding felt quicker and easier (CoffeeGeek). The review measured the hopper at up to about 31 g. It criticized a handle that sometimes needed several tries to lock, a magnetic catch cup that can come loose, and dial markings that are hard to read in poor light. CoffeeGeek's 2025 manual grinder guide made it the top versatile pick (CoffeeGeek).

Strengths and limitations

What stands out

  • 12.5 µm clicks, fine enough for espresso and not tedious for pour-over, per CoffeeGeek.
  • 590 g, listed at 17 × 18.5 × 5.2 cm.
  • Carrying case included.

Limitations

  • 25–30 g capacity.
  • Dial hard to read in dim light, with no rotation indicator.
  • Less specialized for espresso than the J-Ultra.

Alternatives

Our recommendation

I'd point most people choosing one hand grinder for mixed brewing to the X-Ultra, unless they regularly grind more than 25 g at a time.
