HARIOCeramic Coffee Mill "Skerton" (Japanese Instructions)

Very well made. Easy to use. Grinds the beans perfectly.

The hidden feature is the attachment thing for the crank is essentially a hex nut. If you get a 7 mm (if I remember right) hex adapter for your cordless drill and run the drill on slow speed, you can avoid the tedious manual cranking, even during a power outage.

I got this because it came up again and again when I Googled "best manual coffee grinders." It replaced a cheap cylindrical metal grinder made in China, which broke after a month, so that's all I have to compare it to.The best thing about it is the wide hopper. It grinds more coffee at a time, and therefore it grinds fast -- 4 tablespoons of beans in 1-2 minutes, versus 4-5 minutes with my old grinder. It's easy to take apart and put together. It's fairly easy to clean, again because of the wide hopper, but you will need a bottle brush to get every nook and cranny. It may take practice to find the grind adjustment that suits your preference, but once you do, it's easy to set it again after you wash it.The drawback of the wide hopper is that the waist of the grinder is too big for the average female hand. It's easy to lose your grip on it. After dropping it once, I started holding it braced against my body, to keep a better grip on it, and over a kitchen counter, as well, so it wouldn't have far to fall.It has other drawbacks. Grinding coffee gives it a static charge. That didn't matter with my old metal grinder, but it makes the coffee stick to the glass receptacle of the Hario. I have to hit the receptacle against the counter or with a knife handle to get all the coffee out. The rubber skirt of the receptacle, intended to cushion the glass against breaking, tends to just fall off.And it has one major design flaw: Grinding loosens the nut that holds the handle on. I discovered this when the nut just flew off mid-grind. Now, after every 20-30 seconds of grinding, I stop to retighten the nut.Bottom line, I don't understand why it keeps getting on "10 best" lists. It has its flaws. However, once you get used to it, it's a sturdy, hard-working grinder that makes delicious coffee.Pro tip: My cell phone translation app translated the Japanese instructions, no problem.

We suspected our original unit was worn out. That was confirmed when we bought a new one for our son to take to college. This was confirmed when the new one took 3.5 mins to grind 60 g of coffee, whereas the original was up to 12 mins. So, I bought this one to replace it. I hope to wear this one out, too.

It takes a little time to fill up the glass jar, just go slow and steady. I used google translate for the instruction sheet and adjusting the grind level was no problem. You can also go to youtube for instructional videos

I use this product just about every day to grind coffee for both a pour over and for a Moka pot. It’s a capable grinder.The main issue I have is adjustment for courser or finer coffee. The way that you adjust this particular grinder is by pulling up the rubber top piece, unscrewing a nut that holds the handle onto the grinding mechanism, and then removing this small metal piece. The small metal piece is keyed so that way it locks into place when the handle is turned, causing the burrs to spin. Without this small, very easily lost (I dropped mine in my sink disposal once) piece, turning the mechanism adjusts the burrs for finer or courser grounds.THE ISSUE: there are NO markings for how fine or course relatively the burr is set to. You have to eyeball it each time, and that’s kind of frustrating. Maybe there are instructions for it in different models, but mine were all in Japanese…Also, grinds aren’t typically 100% consistent as there will be some larger chunks here and there, but not very frequently.Edit: after one year of frustrating and diligent work the bur just shattered. Yay

I came to buy a cheap grinder and ended up going down a rabbit hole of grinder types and it was very overwhelming. Apparently the cheap electric grinders I've been using are crap. I decided to go manual as I didn't feel like paying $80+ for a grinder at the moment and the ol' internet recommended this one. So I'm still not sure if I'm grinding right because this thing is a little tricky to use, but my cheap metal filter pour over cup of coffee has definitely gone from being a semi sludgy mess to something much better. I bought this to grind for cold brew which I haven't done yet, but I'm hoping for good results. If not I'm going to feel like a dummy grinding for 8 minutes to get enough grounds for one batch. Yes, the instructions are in Japanese, but a quick google search will tell you what you need to know. This is probably not the best for making a large pot of coffee in a hurry unless you pre grind some (which maybe defeats the purpose of having freshly ground coffee) but for one or two cups it really doesn't take very long. Another positive thing is that this will screw onto a regular mason jar so for larger batches I won't need to grind, empty the container, and then grind more.

it's a solid product and it does a good job, but definitely not recommended for a novice or someone who doesn't know their way around mechanical devices as it is a bit more nuanced than your typical hand grinder
