Pros and cons
Pros
- Kaffeemacher found espresso excellent, complex, dense and fruity with a silky texture across light to dark roasts.
- Kaffeemacher timed 18 g in about 7 seconds.
- Kaffeemacher found excellent repeatability: returning to a setting by eye landed within a few micrometres.
- Kaffeemacher praises the solid aluminium build and notes CE certification and a dealer and service network.
Cons
- Kaffeemacher measured 0.9 g total retention, 0.3 g permanent and 0.6 g temporary, and calls that rather high for a single doser.
- Kaffeemacher measured 81.0 dB, while iDrinkCoffee repeats a maker claim of below 65 dB.
- Kaffeemacher says the scale markings are small and far apart, so a tiny turn can shift extraction time by several seconds.
- Kaffeemacher says cleaning needs a screwdriver up to seven times, and the zero point must be reset whenever it is opened.
What owners report
- Retention complaints. One CoffeeSnobs poster calls retention fairly bad, dislikes hitting the bellows hard, and says he would rather have a DF64 or a Niche Zero.
- Fixed high speed. CoffeeSnobs posters find the fixed 1950 RPM an odd choice and suspect it targets cafes, and one expects it to become espresso only.
- One failure report. One CoffeeSnobs poster called it a useless home grinder after it stopped working, and says the retailer offered only a restocking fee.
What experts measured
- Kaffeemacher measured a main particle peak of about 210 to 215 microns in the espresso setting and about 35 g per 10 seconds.
- iDrinkCoffee lists a 1950 RPM motor, a 34 g top, a 105 g hopper extension and 4.8 kg.
Alternatives
Niche Zero
One CoffeeSnobs poster calls the X64 SD a Niche Zero but uglier, and would rather own the Niche or a DF64.
