Great hand grinder
Excellent quality materials and manufacture—not the cheapest but I would say well worth the cost. The only thing that could be improved would be making the grind setting more standardized. You do need to play with the settings a bit, I think because when assembled the guide numbers may not quite match. But it is very easy to figure out, and the grind is quite consistent and results in very good coffee with good quality beans. I would not say grinding beans by hand is easy, at least to get started, but the burr seems very sharp and good quality so after a few turns it smooths out and works very well. You can also use an electric screwdriver/drill if you wish (the handle fits on magnetically on a hex piece the same size as changeable screw bits) but you will need to hold tightly at the start. With the electric screwdriver you will get some static sticking of the grains in the grounds container that you don’t get with the handle, but a couple taps on the counter and they settle and will pour right into the coffee basket. The body, bur, and the ground container are good quality metal, some plastic on the spacer for the handle and the top cover. The ground container at the bottom makes a good place to weigh your coffee grounds then pour into the top. This greatly exceeded expectations and seemed better than any hand grinder I could find a youtube review of—highly recommend if you want to grind your own coffee.

Good Quality Hand Grinder
I have wanted to make better coffee at home and this grinder has been very helpful to that end. I was convinced to get a grinder from this company after James Hoffmann’s positive review and I decided to get the best model available.I appreciate the features and attention to detail from the solid metal body, the exterior adjustment with clear markings, and the comfortable wooden handle. I find that it has the perfect capacity for a single serving of pour over (18 to 20 g) and I actually use it to grind larger quantities of beans for pour over by filling, grinding, and emptying multiple times. The grinder is very ergonomic and easy to use – I haven’t had to strain or struggle to grind most beans at course to medium fine settings.I will note that there is some static buildup (this is an inherent problem with grinding coffee and not a flaw specific to this grinder) but I just let the grounds rest for a minute or two and then firmly tap the side of the grinder with my hand a few times which helps knock the grounds loose. Although I still consider myself as an amateur home brewer, I believe that this is a great entry level quality grinder that is easy to use and priced competitively in what seems to be a rather expensive coffee gear market.

Really fun unit! But in-box instructions are ABYSMAL!
This is a surprisingly fun unit to use once I got it up and running. Seems very well built, I really like using it and I’m not even a coffee drinker! I got it for a friend. However, the in-box instructions are TOTALLY ABYSMAL, not thorough at all and extremely confusing. So here are my tips, observations, and recommendations:1) DO NOT GRIND ON LEVEL 1, AND 0 CLICKS!! YOU COULD DAMAGE THE BURR BIT: You need to dial to at least Level 1, and 16 clicks to use the grinder. You could theoretically grind as low as Level 1, and 1 click, but I’d personally avoid it and only go as low as Level 1, and 16 clicks. You can observe that if you set the dial to Level 1, and 0 clicks, the crank handle will not swing freely, so I suspect the cone burr is grinding against the outer ring-burr and possibly damaging the cutting edges.2) DO NOT REGRIND PREVIOUSLY GROUND COFFEE. Meaning, if you grind some coffee into large particles, do not re-insert that ground coffee into the hopper to grind it finer. If you do, small coffee particles could lodge in the inside grooves of the dialing mechanism or in the axle mechanism and clog its operation. So only put whole coffee seeds (beans) in the hopper.3) EACH LEVEL AFTER LEVEL 1 = 60 CLICKS:Level 1, and 0 clicks = 0 clicks. (Don’t grind on that level, you could damage the burrs. You should be at, at least 16 clicks to use grinder).Level 1, and 16 clicks = 16 clicks (super fine grind, for espresso).Level 2, and 2 clicks = 62 clicks.Level 3, and 10 clicks = 130 clicks (used for pour over coffee).Level 4, and 55 clicks = 235 clicks (coarsest grind possible, used for French press coffee).The larger the level number (e.g., 3 or 4, the coarser the grind).The smaller the level number (e.g., 1 or 2, the finer the grind).(though I am not entirely sure about my “level” calculation. There might be a “level 0” and I am counting level “0” as level “1”)4) GRINDER LID HAS TWO POSSIBLE CONFIGURATIONS: The grinder ships in the “Drill Bit” configuration where you can use the grinder with a cordless drill. Even though I suppose most people would not be using a drill, I think the manufacturer ships it in this configuration because to ship it in the “Manual Grind” configuration would require the crank handle to be attached to the plastic hopper lid and the handle would not pack efficiently that way. You can also grind coffee manually in the “Dill Bit” configuration, but it is harder to remove the plastic hopper lid to insert the coffee seeds (beans). The “Drill Bit” configuration has a large black “O” ring on the inner lip of the plastic hopper lid. This is so the hopper lid stays firmly in place when using a cordless drill. The hopper lid will NOT rotate if it has the black “O” ring on it.The “Manual Grind” configuration, on the other hand, requires you to: 1) REMOVE the black “O” ring from the plastic lid (I used a small wooden toothpick, but you can use any non-sharp object so that you don’t cut into the “O” ring since you may want to use that “O” ring later. 2) Insert the crank handle into the plastic hopper lid, inserting the end that looks like a ratchet-socket into the plastic lid. 3) Remove the small white “O” ring from the plastic bag that is attached to the instruction card and slip the white “O” ring over the end of the ratchet-socket end of the crank handle from the inside of the plastic lid and allow the white “O” ring to fall into the pre-cut groove located approximately 1 centimeter from the opening of the ratchet-socket. The small white “O” ring will now act like a locking pin or locking clip to keep the crank handle “permanently” connected to the hopper lid. In this way you can easily remove the hopper lid and the crank handle together as one unit. In the “Manual Grind” configuration, the plastic hopper lid must freely rotate with the crank handle. If you forget to remove the black “O” ring, then the plastic hopper lid will stick to the canister body, and you will not be able to grind any coffee.5) DISASSEMBLE AND CLEAN OUT FACTORY DUST PRIOR TO USE: The instructions do not say anything about pre-cleaning, however I noticed quite a bit of what looked like residual factory dust in the hopper, coffee canister, and even on the cleaning brush itself. So, I disassembled the unit, blew out the dust with a compressed air machine, and then wrapped a large 70% alcohol cloth on a wooden chopstick and wiped out all the residual dust I could see. I gently wiped the burrs in the direction of the cutting edges (so as not to cut myself), however this may result in strands of alcohol pad being left on the burr edges. So, I then cleaned the cleaning brush with the alcohol wipe and then used the brush to brush off any fibers left on the cutting burrs and then used my compressed air machine to blow out any debris. I did not clean the axle with alcohol, nor the ball bearing donut-ring since I did not know if there was any lubricant on those parts and I did not want to wipe it off in case any lubricant was there.6) DO NOT USE WATER TO CLEAN THE UNIT: It seems any water that enters the unit may cause the parts to rust. Hence the manufacturer recommends only using the included brush to clean the unit. I used 70% alcohol wipes to clean it, but there was nowhere that I saw where alcohol was recommended or prohibited by the manufacturer, so use alcohol at your own risk.7) THE “PC” IN “PC LID” MIGHT STAND FOR “POLY-CARBONATE”: I’m just guessing that is what it means…It just bothers me to see abbreviations and not know what they stand for. “Poly-carbonate” is my best guess.8) FOR DISASSEMBLY, TWIST TO LEVEL 4, AND 55 CLICKS AND USE AN OLD, SMALL PLASTIC CAP TO HELP PUSH UP THE AXLE: Twisting the grinder setting to maximum “coarseness” causes the cone burr to protrude from the bottom of the unit. Do not go beyond Level 4, and 55 clicks. When the cone burr protrudes, you can then push it up so as to remove the retaining clip from the axle at the top. To easily push up the cone burr, I used an old plastic, circular cap (like something from an old medicine bottle or a juice bottle. It should be no more than 1.5 inches in diameter and can be 0.5 inches tall). I placed the cap on a hard surface and then put the grinder over the cap and pushed down. This allowed the axle to pop up where I could remove the “C” clip (or “U” clip) with a wooden toothpick. Take care not to let the “U” clip fall into the burrs, so you may want to tilt the unit upside down or use some plastic tweezers to remove the “U” clip and let it drop out.There are disassembly instructions and care instructions on the KINGrinder website, but they are so dang hard to find. They should have put a QR code in the shipping box so customers could go straight to the instructions on the website as the in-box instructions are ABYSMAL! But even their website instructions are poorly written. I don’t think Amazon allows me to insert the links to their website though. If you have questions or want more photos, just post a question on the Amazon page and I can provide more detail.Otherwise, it is a great unit and I am glad I bought it.

Long Term Review of the Kingrinder K6
I’ve been using this grinder multiple times a day for about a year now. My primary use cases are V60, aeropress, french press, and espresso. Bottom line is this grinder is excellent in every way and could be all you ever need to make *any* type of coffee. I’ll break up my thoughts by brew type to give you a better understanding.French press: I’ll start off with this, because I think it’s by far the strongest category for this grinder. The reason being that the grind uniformity for very large grind sizes (like for french press) is ridiculously good. The flavor profile is unlike anything I’ve gotten from other hand grinders or electric grinders. Additionally, with the large burrs, the grinder makes short work of grinding and it isn’t physically difficult either.V60/Aeropress: I’m doubling up these categories because I think they demand similar things in terms of grind profile. This is the most frequent type of coffee I drink and maybe the most challenging for this grinder. I have had great cups from these methods when using this grinder, but I find that dialing in for a consistently good cup can be oddly difficult when using new beans. I think I may have been spoiled by the level of quality this grinder is *capable* of, so if it’s anything less it’s noticeable right away. Overall I advise to adjust grind size in 10 step increments (or coarser) until you find something acceptable.Espresso: Finally espresso. this grinder is very much capable of espresso, the increments are plenty fine enough and go small enough for just about any arrangement (I typically run light roast and a bottomless portafilter personally). I think this is where the grinder really comes alive, as the tuning of the steps is perfect for dialing in a good shot and I usually only need to pull 1 or 2 shots before it’s good to go. I wouldn’t say the flavor is the absolute pinnacle per se but the character of the beans really shines through in every shot.Overall: Excellent (solid metal) built quality, excellent user experience, excellent adjustment system, excellent reliability and longevity, excellent price. There isn’t really much to complain about, but if I had to, I’d say I don’t like the threading on the catch can, I wish it was a shorter throw, or better yet a magnetic attachment system. I don’t see a reason to get anything better than this, the taste is better than most cafe drinks I’ve had and it doesn’t seem like it’ll break anytime soon. Highly recommended.Edit: Kingrinder is really starting to gain some traction now that James Hoffman has done a video on them. Be wary of paying too much for this grinder, I paid $100 when I purchased mine in March 2023, but there are many options that are better in the $200 range from 1zpresso and other companies that come with more creature comforts. Do your own independent research!

Works great and easy to use.
I’m really happy with this grinder. It’s very easy to use and does a great job.I did a great deal of research before settling on this model. Ultimately, what appeals to me the most is that you are getting, and paying, for a conical burr movement and nothing else…it’s simple and efficient. I also like the straight forward mechanism for settling the grind settings and the sturdy construction.

Precision and convenience: great all-round grinder
After using the Kinggrinder for over three months, I can confidently say it’s a highly reliable, precise, and convenient choice for coffee enthusiasts. I opted for this model over a competitor that is reportedly easier to clean because I preferred the external clickable adjustments on the Kinggrinder. This feature makes it incredibly easy to switch between grind sizes—perfect as my partner prefers a finer grind while I go for a coarser one.While I’m not new to the daily grinding of coffee— I previously used a (considerably loud) old-school electric grinder with a graduated burr —the grind consistency of the Kinggrinder is truly impressive. The grounds it produces are remarkably even, which enhances the overall quality of the brew.Its compact and portable design has made it a great travel companion even across continents. While I haven’t yet opened it for cleaning —admittedly a slightly challenging process — the habit of lightly wetting the beans prevents static and ensures minimal residue buildup. I anticipate needing to clean it only about twice a year, and when the time comes, I’m happy to follow a YouTube tutorial to get it done. Overall, this grinder has exceeded my expectations in both performance and convenience. Highly recommend.

Solid Grinder! Highly Recommend … lets talk grind size
This is my first grinder and thought it would be best trying a manual grinder out over electric. I thought it might feel like a chore grinding it manually but its actually quite nice. It can be a bit of a workout for a finer grind size. It feels solid and looks ‘premium’, but those things don’t really matter. What matters most is reliable grinding. I have used it for roughly 3 months now and have tried out various beans. No real issues, and I am very satisfied with the results!The only thing I wish it did differently was use magnetism to hold the bottom portion on instead of having to screw it on and off all of the time. Aside from that its great. I’ll break things down into espresso and pour over coffee.Espresso ExperienceBe prepared because there is certainly a learning curve. The recommended setting for Espresso suggest 40 clicks. But what size portafilter is that for …58mm? What amount of coffee is it assuming? 16g, 17g? etc. These things matter. A LOT. If you use less of a dose you need to grind finer. If you have smaller than 58mm then it needs to change as well. So my advice is be patient with trial and error at first.Needless to say 40 clicks produced really sour espresso the first few attempts. It wasn’t nearly fine enough. I usually end up in a range of 35 – 27 clicks depending on the coffee and age. For me I have a 58mm with 17g dosage. Keep in mind you will likely have to grind finer the longer you have the coffee to maintain the taste you are looking to achieve. My method is to grind too fine where the coffee fails to come out and then dial it back from there. Then I usually hit the 25-30 second range for time it takes to brew a 1:2 ratio.Pour Over Coffee ExperienceThis one I just started to play around with as of the last two weeks. I can definitely taste the difference based on grind size but I have yet to grind as coarse as the recommended 100 clicks. I am still in the 50ish range and will work my way up. I can’t definitively recommend a grind size for pour over coffee yet. But overall, this grinder can handle pretty much anything you can throw at it.If you can snag this thing for around $100 and don’t mind the manual aspect then I am sure you will be happy with it.

Consistencia y sabor esperado
Es muy bueno… la consistencia en la molienda es la esperada. Entiendo que hay productos mejores, pero por el precio éste está muy bien. He probado el mismo grano en cafeterías de especialidad (con molinos “mejores”) y luego lo hago en casa y el sabor no es muy diferente. Sí siento que el molino se traba con frecuencia con los granos de tueste medio, pero nada que un ajuste en la fuerza con la que se mueve la manivela no resuelva. En conclusión, un muy buen molinillo.
