  1. Simply loving it. Grinding results are absolutely consistent and superb in taste. Step size of the discrete grinding level is sufficiently small to dial in any roast I tried so far, even those which require a rather small grind size.

    One remark: Upon purchasing I was a bit disppointed that the “iron grey” color variant was no longer available. However, this changed completely while working with the “silver” grinder. Over the first weeks, the silver color acquires a lovely golden shimmer which makes the color an outstanding choice IMHO.

  2. High quality grinder very well made, I use it for my Gaggia Classic Pro for espresso, It’s very good that you can precisely adjust what you need for espresso or other methods grinding is fast around 30-45 seconds for espresso you can not go wrong with this grinder everything is great.

    I am very happy with this purchase thank you 1ZPRESSO outstanding workmanship and design.

  3. After buying a Cafelat Robot we looked for a suitably capable grinding device for 100% manual espresso brewing and are very happy with our choice. We use the JMax as our main grinder on a daily base now. It takes less than a minute to grind 20g of beans on the finer end of the scale. The retention varies from zero to a little bit. It doesn’t worry us either way as the brush included quickly takes care of it.
    Despite the many grind settings the JMax offers 1Zpresso made it surprisingly easy to see which exact setting is used (combination of dot layers on the indicating arrow and around the ring), that is especially useful when reassembling it after cleaning. Overall we are impressed with high build quality and great performance.

  4. Basically perfect. The grinding quality is extremely high and versatile. I’ve had it for half a year and I’ve been using it almost daily for filter coffee and for moka pot, and I love how easy it is to switch between grind sizes. Just turn the big dial, one second and it’s done.

    It’s quite fast at grinding and has a long handle, so not much force is required for grinding light roasts.

    The magnetic cup is really comfortable to use, and it has never brought me any issues. It’s also really easy to take apart completely and clean, no tools required.

    The included travel case is quite easy to carry inside my backpack and very convenient.

    I was going to get the JX-pro, which seemed really good, but this one is better in every single respect.

  5. I have a Brevelle Barista Express whose grinder is quite loud. My wife and I live in a small condominuim, I purchased the J-Max so as not to wake my wife early in the morning. The J-Max has become my go to grinder. it’s superior consistant grinding combined with the 8.8 micron steps makes dialing-in espresso easy. With the exterior adjustment ring I can easily move to different coffees or brewing styles and to return to the previous grind with no loss. A great grinder!

  6. I primarily use mine for espresso, but have also done pour over, drip and french press.

    This grinder works great! Absolutely no issues to date. I’m around 9 pounds of coffee through it. It grinds well, the build quality is excellent and the catch bin is the perfect size for a 58mm portafilter.

    If you’re wondering what the rubber band is for, I think it’s meant to give you grip. I have mine on the top part about 1/3 down and it helps a ton when I’m grinding a light roast and need to put some more torque into it.

  7. I got the J-max to go with my flair for traveling. I love everything about it. Fast, consistent, beautifully made, beautifully packaged. Easily adjustable for any grind from Turkish to French press or pour over. Excellent piece of gear.

  8. Top notch. Replaced my old Zassenhaus. This grinder does the job in half the time. This is precision machined from the burr to the housing. Micro-step adjustment gives absolute control of grind size. I am using it for espresso grinding only and it pairs perfectly with my La Pavoni Europiccola.
