1Zpresso Q Manual Coffee Grinder, Mini Slim Travel Sized Fits in the plunger, Stainless Steel Conical Burr, Numerical Adjustable Setting for Pour Over French Press Cold Brew

expensive but worth it. does a great job. solid construction.

It fits well inside an Aeropress and it is the right size to grind the perfect amount of coffee for a single cup. The grind size is consistent, and the adjustment increments are small enough for a good amount of precision. The burr is the same one used on some of their more expensive grinders, and it works well. The folding handle is not the most compact design, but it does reduce the profile a bit when stowed, and keeps the grinder from falling out of the Aeropress. It feels solid and well made. The quality exceeds the price, and it should last for years. If you're using pre-ground coffee or a cheap blade grinder in your Aeropress, this is a significant upgrade and will help you make a much better tasting cup of coffee.

Does not grind fine enough for espresso use. Refund process is horrible.

Great product. Fits perfectly in the aeropress standard barrel making for easy stirage. My only complaint is that if you leave the grind handle on while it's empty, it tips over, so you have to separate them on your counter.

UPDATE: I was able to disassemble the burr by unscrewing the click-dial and removing it and the click-plate. The click-plate is keyed with a slot for the shaft and a cylindrical plug that seats in the bottom of the burr. Rotating the heptagonal burr allowed me to rotate the click-plate by 180° when reassembling, so the adjustment knob now points to 0 (zero) when fully screwed in (what 1Zpresso denotes the "zero-point"). This issue with the numbers on the dial unexpectedly decreasing rather than increasing when dialing a coarser grind remains nonetheless. *** ORIGINAL REVIEW: *** I have used similar (and similar-sized) hand-grinders, including Porlex, Kyocera, Timemore Chestnut C3, and VSSL Java 2.0. The 1Zpresso Q series feels most similar to a a combination of the Timemore Chestnut and the VSSL. The fit, threading, construction, wall thickness, bearings, handle, shaft stability, and grindfeel are all good and as I expected based on the price point, stated features, and other reviews (not just here). The adjustment dial has 30 clicks per complete revolution, so the adjustability is already finer-grained than either the Timemore Chestnut or the VSSL. There are a few ... idiosyncrasies, shall we say, which lead this reviewer to fewer stars than the maximum. NOTES: —I received a sealed and apparently new grinder with all accessories, with no obvious defects or signs of use, as some other reviewers have reported. —The main grinder body appears to be anodized aluminum/-ium; the color is slightly warmer that what is most often called "silver", but not so warm that it's gold or rose gold. It's most like what would be called "nickel-silver" if it were a smooth metal plate or solid finish. —The metal handle is a more neutral color and appears to be brushed stainless steel. The handle is permanently attached to the frosted plastic lid, similarly to the Timemore Chestnut C3. —No user manual arrived with the grinder, but I located one easily on 1Zpresso's website. —The 1Zpresso Q fits into the plunger of my Aeropress as claimed. Neither the Timemore nor the VSSL so fit, as they are slightly too large in diameter. —My 1Zpresso Q weighs 472 g on my digital scale, which is just over a pound US. On the same scale, the slightly larger-capacity Timemore weighs a very similar 476 g, while the same-capacity VSSL (including detachable knob) comes in at 426 g (about 1.6 oz US less). IDIOSYNCRASIES: —The numbers on dial at the base of the burr have wrong the rotational sense: When turning the knob counterclockwise, they count down from 0...9...8...7... instead of counting up from 0...1...2...3.... (That is, they are arranged like an analog clock face, but there are only 10 numbers). This is backwards from what is expected (one full rotation out plus one additional number stop should point to 1 rather than 9). —The adjustment knob at the base of the burr has a tang that projects out and acts as a grip to turn the knob. There is a circular indentation at one end of the tang that serves as a pointer to the numbers on the dial. That mark is at the wrong end of the tang—when fully closed, the mark points to 5 rather than zero as would be expected. SOUTHPAW ISSUES: —The "folding" handle is designed for the Right-Handed Hegemony. It's a natural motion to press the wooden knob inward with one's right hand and rotate out-and-down to "fold" or out-and-up to "unfold". However, doing the same thing with one's left hand makes the arm/wrist/hand contort in an uncomfortable way when rotating in-and-up for "unfolding", because the handle only "folds" down in one direction rather than both directions. All in all, the above idiosyncrasies do not prevent me from using the grinder, as I do not plan to adjust the grind very frequently, but they do indicate design or manufacturing failures (or both) that I do not expect based on the price point, brand reputation, and other areas of quality, and I am disappointed by that. And, as a lifelong left-hander, I am used to being ignored by designers that either don't know or don't care that some of their customers don't prefer their right hand. But that doesn't mean I have to like or accept it. Thus, 4 out of 5 stars.
