Mahlkönig X54 Coffee Grinder

If you are looking for a hopper-based espresso grinder, you really can’t go wrong with the Mahlkönig X54. Mahlkönig was always the brand on my radar, and while most online reviews cover the initial launch version, it has since undergone a silent upgrade. The performance, grind speed, and overall experience are significantly improved in this updated version.
Performance & Speed: Takes roughly 9 to 10 seconds for an 18g dose with impressive consistency (+/- 0.2g variation).
Grind Quality: Produces extremely fluffy grinds that yield great espresso extraction.
Build Quality: Solidly built and relatively quiet during operation. Compared to my Eureka grinder, the build quality on the X54 is in a completely different league.
Usability: Very easy to adjust, simple to clean, and looks fantastic on the counter.
Retention: Retention is quite significant (around 3g), though for daily hopper-fed espresso use, this isn't much of a practical issue.
Dialing Range: It works best as a dedicated espresso grinder. It is not an ideal option if you plan to constantly switch back and forth between espresso and pour-over.

If you want a dedicated espresso grinder at this price range, I think it's a very relevant option

It arrived earlier than I expected. Thank you very much. The performance of the grinder is also very good and I am satisfied.

Pros:
Great quality grinding
Very quiet
Almost no retention
Cons:
Hoper is too big for home use
A lot of static electricity.
slow - almost 20 seconds for 18 gram espresso basket
Messy - Ground coffee spreads around 20cm radius

This grinder is exactly what I was looking for in a grinder. It makes a good grind for french press down to Moka pot so far. I haven't tried it down to espresso, but I can imagine that the grind will be good.

The only thing I would wish for is a half sized hopper, as I never have that many beans in at one time.

But I think it looks great, feels like a solid build, and has, effectively, a lifetime guarantee.

The portafilter holder module has a stuck screw that prevents me from adjusting it. Basically, the screw head groove has a metal object tightly embedded into it that makes it impossible to lodge a screw driver in it. I have written in to ECS. It has been a few days. No response so far.
