1Zpresso J Manual Coffee Grinder Silver Capacity 35g with Assembly Stainless Steel Conical Burr - Numerical Internal Adjustable Setting

I was skeptical, given that the 1Zpresso J is many times more expensive than my previous grinder. However after two months of daily use, I’m impressed by its solid build quality, the speed with which it grinds coffee beans, and its good looks. It’s a worthwhile investment.My three year old JavaPresse frustratingly met its demise when some of its critical components, made of plastic and held in place with glue, came undone. I was primed for an upgrade and I liked how all the functional elements of the 1Zpresso J were made of metal, which set it apart from some others on the market. I ordered one.This thing is over-engineered. And I love that about it. Made almost entirely of metal, with a surprising heft and featuring tight and precise tolerances, I’m confident that this thing will outlive me.And it works well. In less than 5 seconds and just a few turns of the crank, my coffee beans are prepped and ready for their soak in the french press. Meanwhile, using the Javapresse felt like a workout at times, taking closer to a minute to complete its task and requiring far more rotations of the crank.It looks good. Especially after removing the silicone sleeve.Buy it for life. This thing will confidently grind coffee beans for decades.

After wanting to get more into coffee, doing a lot of research on the topic resulted in the conclusion that buying a grinder to freshly grind coffee beans was one of the biggest upgrades. So, after a ton more research, I had actually settled on the KINGrinder K6, with the consensus being that it was the best bang for the buck. I had also heard that one of the biggest drawbacks of it was the disassembly, that it was very difficult to disassemble and put back together, for cleaning purposes. Since I never owned a grinder before (manual or electronic), I didn't really have any context for what this would mean, hence I took a shot on it. Once it arrived, I was actually quite impressed by it (again, not really having proper context), everything seemed to be extremely well built. But, knowing my personality, I started to look into the disassembly/reassembly issue that I had heard about. After reading manuals, watching videos, and spending a decent amount of (semi-wasted) time learning about all of this, I tried to get the grinder disassembled, and failed badly. No matter what I tried, I couldn't get the pin holding the entire assembly together to come out, of course I was trying to also be delicate with everything as I didn't want to damage anything and risk not being able to return the item if it came to that. After spending enough wasted time and getting frustrated, I decided that it needed to go back, and in that regard I was glad I never got it disassembled, because I realized that it would have been very likely I wouldn't have been able to properly reassemble it afterwards.So, back to the drawing board with more research. Ultimately, I decided to just spend the extra money to buy a 1Zpresso, and I picked the J Manual model because it seemed to be the best bang for the buck one for pourover that 1Zpresso has. The only thing I dislike about 1Zpresso grinders is the very confusing naming and changing of their lineup, for instance the J Manual was actually the Jx from previously with very minor upgrades. When the grinder arrived, it was actually even nicer than the KINGrinder K6 in overall feel, build quality, and impression. The first thing I tried was the disassembly and reassembly, which as I had already researched, was decently easy. Note that it wasn't perfect, once you do a disassembly and reassembly, if you want the number dial to line up with the "zero" of the grinder, it is incredibly difficult to get right. However, if you just use the numbers as a reference point and don't care that zero is zero, then it's not a big deal.I have now since used the grinder almost daily for about a month and a half, and the grinder continues to be a pleasure to use. Grinding is seemingly very easy, satisfying, and foolproof. Everything is machined very precisely, and the entire unit is very solid. Overall, I feel that the item is worth the money paid, which for me is a very satisfying feel.

Without a doubt the best manual grinder I have owned so far, this being my 6th.First, as an engineer, I really appreciate good design, both in terms of looks and function. The bearings within the grinder are the smoothest I have used so far. I think between the bearings, the stainless burrs, and the handle being a little over 5 inches from center of the grinder to center of the wooden grip (longer handle, better leverage, easier to grind), grinding is near effortless.Second, the aluminum housing is very solid, not thin gauge like other grinders. With the smooth operation of the grinding mechanism, the grinder is also the quietest manual grinder I have used as well. Since I am always up the earliest making coffee, silence is golden.Third, this is by far the fastest grinder I have used, grinding in well under half the time of my old Handground grinder. I haven't timed it, but its definitely under 30 seconds with the hopper almost full compared to a little over a minute and a half for the Handground. That's setting 3 on the JX versus setting 2 on the Handground for an aeropress, which visually gives about the same grind.Finally, the grind itself is very consistent in appearance.I would say the only down side, and not big enough to me to drop a star, is that it generates a little static when grinding. The first time I used it, when I unscrewed the bottom receiver, a lot of coffee clung to both the sides of the receiver and the bottom of the burr and was a little messy when I unscrewed it. So what I do now is once the grind is done, while I'm holding the grinder in my left hand, I give it a couple of hits with the butt of my right hand on opposite sides. When I open it up, all of the coffee is in the bottom of the receiver cup.Also, I had to wait for the JX to get back in stock and Anne at 1ZPresso was very helpful answering my questions and keeping me informed on progress, so big kudos to her.To me, having a great cup or three in the morning is a simple pleasure of life, and having the right tools is a key part of making that happen. I would highly recommend this grinder to anyone who feels the same. If you have owned other grinders, especially in the $10-$20+ range, I'm sure you will agree after the first time using it. There's no comparison. It is worth the investment and looks great sitting on my bamboo aeropress stand on my countertop.

The price of this grinder is worth it! I have been using it constantly everyday and it always grinds very smoothly. It allows me to enjoy perfect cup of coffee. The settings for the grinder is perfect and it can grind fine but not too fine. I use it for Pour Over and Cloth Filter which I grind it medium course setting. It is easy to clean and the kit is idea. The material is a great quality and I am happy with my purchase.
