The external adjustment dial with micro-clicks makes dialing in espresso incredibly precise and effortless. Grinding is fast, consistent, and surprisingly smooth with minimal effort. The magnetic catch cup is sturdy and secure, and the included carry case is well-designed. Truly top-tier manual grinder.

This is my third manual coffee grinder (not counting the 3 electric ones), bought for use with a Jeep for permanent living outside the city. I used it with the Commander C40, got confused - it's gathering dust and can't set the step properly. This grinds perfectly right out of the box, the craftsmanship is beyond praise, the burrs are centered, and there's no dust at fine grinds. If I hadn't used JX Pro for a long time, I might not even know about the existence of J Ultra. and yes, -super! There are no alternatives for Jezva at all. On the commander now I grind under espresso for clean jokes without milk. here she came in

I bought it purely for the coffee pot. It grinds medium-roast coffee very quickly and accurately. It's exactly what you need for a Turkish coffee pot. Very satisfied!

Excellent for espresso, make sure it's the 1Zpressso J-Ultra because there is a difference between it and its sister model K. Good luck to everyone.

Very good grinder, much better than the Comandante C40 for espresso. The clicks allow you to adjust the grinding in detail. It's much easier to grind too, requiring less effort.
