  1. 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)!

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

  3. 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.

  4. 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.

  5. 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.

  6. Superior grind quality. Ease od grinding beans for a pourover is impressive. Actually i grind my batch for my brew almost as fast as my previous Baratza Encore. Only 2 things which i find should be upgraded. The user’s manual does not quite good explain the calibration process (how to determine the exact zero point) i fained help from a YouTube video. Next, the material od the runner blower which i use for cleaning residual coffee from the grinder is getting dirty very easily (after 1 use it’s covered with coffee dust, hard to be taken off). Besides that – superior grinder, the quality od the whole package gives na impression of having a quality experience.

  7. Perfect, well crafted piece of art. Love this grinder.

  8. I’ve been using the K-max for half a month now, and it requires a bit of effort when grinding for espresso, but the resulting grind particles are impressively uniform, leaving me highly satisfied. When used for pour-over grinding, it grinds more effortlessly. The quality is excellent, and the shipping speed from Taiwan to Canada was remarkably fast.
