What a marvelous little grinder! It feels robust in the hands. I've made ten 18-gm shots with it, using medium roast beans. It was "dialed in" after four cups, starting at the 14.0 setting as recommended in the online table and backing off by two clicks (coarser) for each subsequent cup --- trial and error here was reliable, and the espresso is great. My grind time is 30--35 seconds, without rushing. The torque in holding the grinder is notable but manageable. Durability remains to be seen --- and it had better be good at the price --- but the grinder feels sturdy. The magnetic attachment for the lower chamber is effective and convenient.Quibbles: (1) The zero setting from the factory was 3 clicks less than where I later put it; (2) the grind is coarsened by turning the adjustment wheel clockwise, which feels counterintuitive at first; (3) the upper chamber is narrow and takes practice to fill without bouncing out a couple beans; (4) about .5 gm of grounds stays in the upper cavity of the lower chamber and needs to be brushed into the filter; and (5) the instructions for unfolding handle, which are important, are at the end of the online manual, where they are easily missed.

This Grinder rocks! Its smooth and super adjustable! I use it for Espresso and it works well! I'm now saving lots of money by making my Espresso at home rather than going to a shop. It is larger than a C2 chessnut grinder, which was great for pour over, but lacked for espresso. The bigger size gives room for your hand under the crank. You will need that so you are not gripping and turning the magnetic basket. The magnetic basket is nice and fairly strong, but I feel that could be a failure point at sometime in the future. Taste is good and grind adjustment is very minimal so you can dial in. Better than spending several hundred dollars for a mechanical grinder, only takes about a minute or less to do a complete superfine grind. Price is expensive, but not really if you are getting into the espresso coffee game. For practicality I wouldn't go above this grinder.

I love everything about this grinder. Perfect heft, external gauge that's very easy to quickly set yet not too easy to accidentally change, good speed and capacity, and very little retention. And definitely loving the magnetic catch cup, which is very secure yet easy to remove when done grinding, as well as the sturdy folding arm and comfortable wood knob. Plus, it looks great, and the case it comes with is functional, very well made and also great looking.After getting this and putting it through its paces, I'm no longer surprised at all at what they cost. Well, maybe a little surprised they don't cost even more than they do. Really makes my old Porlex Mini that I bought for Aeropress use nearly 12 years ago seem like a cheap toy.Using this for brewing espresso with a Flair Pro 3 but might try some other coffee grinding uses with it at some point, while of course keeping in mind that this one is optimized for espresso.

As someone who revels in the art of coffee-making, I couldn't resist adding the 1Zpresso J-Ultra Manual Coffee Grinder in Iron Gray to my collection, especially for travel purposes. My initial intent was to pair it with my OutIn Nano portable espresso machine for those on-the-go moments. However, what I didn't anticipate was how the J-Ultra would transform my home brewing experience, challenging the reign of my beloved Niche Zero grinder.**Build Quality and Design:**The craftsmanship of the J-Ultra is nothing short of impressive. Its robust iron gray body not only exudes an air of sophistication but is also built for endurance. The foldable crank is a genius touch, making it not just space-efficient for travel, but also a delight to operate. The ergonomics are spot on, providing a comfortable grip and smooth grinding action that makes the manual process not just bearable, but enjoyable.**Grinding Precision:**One of the most standout features is its remarkable precision. While I have always appreciated the accuracy of my Niche Zero, the J-Ultra surprised me with its ability to make very precise adjustments. The shifting mechanism, allowing changes of as little as 8 microns, lets me dial in the perfect grind size with an almost surgical precision. This level of control is a dream come true for any coffee enthusiast looking to fine-tune their grind to perfection. The pyramid scale on the dial is supremely helpful to understand how many rotations you're on so there is no need to restart at #0 to redial.**Performance and Experience:**Grinding beans with the J-Ultra is not just a task, it's an experience. There's a unique satisfaction that comes from manually grinding your beans, and the J-Ultra elevates this experience. The consistency of the grind is commendable, rivaling even the best electric grinders. Whether it's a fine grind for a rich espresso or a coarser one for a French press, the J-Ultra delivers with remarkable consistency.**The Journey to Find the True J-Ultra:**Navigating through the mix-up with the 1Zpresso J-Max in reviews was a bit of a challenge. With the J-Ultra being relatively new, authentic reviews are scarce. But after sifting through and finally getting my hands on the real deal, I can assure any prospective buyers that the effort is worth it.**Conclusion:**The 1Zpresso J-Ultra Manual Coffee Grinder is a testament to the beauty of manual grinding, blending precision, quality, and aesthetics into one compact package. It has not just been an addition to my coffee gear; it has revolutionized my coffee ritual. Whether you're a travel buff looking for a reliable companion or a coffee purist seeking to elevate your home brewing game, the J-Ultra is an investment you won't regret. Highly recommended!
