  1. Owning a C40 Mk4, with RedClix, I was very interested to see what the 1Zpresso K-Max would deliver. The choice between the J series and the K series was a challenge, I have tried a JX Pro, however the K-Max was refined in a number of areas; that of the external adjustment.

    I love the design concept of the external adjustment and the ease of which to reference your setting – a Brilliant setup. The K-Max also has a larger aperture to allow beans to flow into the chamber without getting caught up, and the magnetic catch-cup is a wonderful addition.

    Testing the grind out on my Rocket Evo, obtained some beautiful pours.

    I took the grinder to my friend and coffee Roaster at Siboni’s coffee to test out, he was very impressed by how well the grinder felt (when grinding) and overall result in the cup – for a hand grinder, this was impressive.

    The design of the K-Max certainly has given the Germans a challenge to beat now with the C40.

    If one slight criticism, 1Zpresso has a large number of hand grinder models to choose – this does make selection quite challenging. The 8.8um adjustment on the J-Max is tempting, the 12.5um adjustment of the JX-Pro is perhaps something to desire on the K-Max.

    Overall, very impressed. I do appreciate that the K-Max comes with a case, something that the C40 does not (as well as it’s lack of reference for the point of adjustment), so this is certainly something that 1Zpresso has refined it’s design.

  2. Impressive results with both filter coffee and espresso. If you don’t mind the manual grinding, at the moment it might even be the best grinder on the market for under 1000$ (including electric grinders). Awesome build quality, great workflow, low rpm’s, single dosing, low retention, very fast for a hand grinder, incredibly clean and complex cup profile, even used it for flow profiling with our UnicaPro with great results (which is normally paired with a Key grinder so the stakes were high)!

  3. Really really fast delivery even international shipping in Korea.
    It’s not nessassry to say about product. you already know

  4. This K-Max is as close as you can get to the perfect grinder. Grinds very fast, great ergonomics, quick release catch-cup, and external adjustment ring with more than enough grind settings. I don’t know what else you could do to make it better. Well worth the investment.

  5. Super happy w/ K-Max. Used daily 5 months. Mainly for AeroPress w/ paper or stainless filter. Easy to turn the crank and magnetic cup works great.
    Pro Tip: Avoid electrostatic charge and mess from ground beans. Spray light mist of water onto wall of measuring cup then shake to lightly moisten outside of beans. Zero static charge of grind makes for easy pouring into mill hopper. Cup and burrs barely need dusting afterward.

  6. Excellent grinder, and super portable. Fits in a water bottle pocket for travel. Adjustment is precise and easy, but doesn’t happen unintentionally as with the Lido. Requires much less strength to use as well.

  7. loving it !

  8. This is a wonderful grinder. It produces very sweet, clean cups with Chemex and Clever Dripper, with just about any roast level. Be warned that if you grind towards the lower end of the scale (4 and below), it takes quite a bit of effort to grind, you’ll really build up your arm strength. But it’s extremely well made and is a joy to use and own
