  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. Excellent grinder. Makes the best cup of coffee I’ve ever had. The only issue I have is buying form 1zpresso, they charge you a PayPal fee and it’s NOT refundable if you cancel your order. They don’t tell you this. You have to find out on your own. They won’t refund you the full amount you paid when you first place your order. I changed my mind and cancelled my order for a JX and bought a grey Kmax. Change my mind again and bought a silver Kmax because I was worried about scratching the grey one. Anyway. They charged PayPal fees all three times and they won’t refund these fees. Just be aware when you’re placing your order.

  7. Fantastic product! Does exactly what it is supposed to do and is so easy to use.

  8. I really love this grinder. Huge upgrade from my Baritza Encore and I can use it for travel. The brew from my AeroPress is so much better. I need to use less coffee to get the same strength as before. Remembered some videos I’d seen where people sprayed their coffee beans with water to reduce static which helped.

  9. Fantastic quality hand grinder, especially for the price, great packing and the fastest shipping I have every gotten from China, literally a few days to South Africa. Highly recommended. Product is way better than any equivalent I could purchase locally, even at much higher prices. I’m still breaking in and dialling in the settings for my tastes, I would say that the fineness of the graduations is even overkill, certainly more than adequate, and the system is solid, with no likelihood of unwanted shift between settings. Lots of good design, like the hex top that matches standard drill hex bits in case you’re wanting more speed and is also just more robust than the cheaper wobbly drive handle mechanism in the model this replaces which cost me an absolute fortune in Germany (I didn’t realise that the fancy german packaging was just rebranded cheapie that I could have gotten off of aliexpress for 1/5th of the price, but that’s another story). I still seem to get some uneven grind (i.e. fines), so can’t yet totally assess the quality of the burr designs, but there is no sign of any wobbling or flex in the mechanism so it’s definitely not caused by that. All in all I’m currently very happy with my purchase.
