I don’t want to sidetrack the thread too much but in short I have a love/hate relationship with the x54. As an on-demand espresso grinder that looks good and gives fantastic results in the cup, it’s ideal. To be fair to it it’s been great for the past month or so.
I just find the adjustment ring too small and firm to make fine adjustments, and that coupled with the enormous amount of purging required when changing brew methods means it doesn’t really work as a ‘do-it-all’ grinder as it’s advertised. So it’s ultimately just a set-it and forget-it grinder of which there are better choices at the price point.
With a time-machine I’d have just kept my Mazzer because it effectively does the same thing but better, or done the smart thing and bought a Niche!!
