My star rating is at the end, apologies if the review structure is all over the place.
This is my 1st manual grinder. I primarily bought this so I could 1. start making espresso for americanos at home when I ordered a flair, 2. to move on from your regular blade grinder because of inconsistent grinds for my french press.
I didn't buy a flair because I'm still mulling over getting a Flair Signature that 8ounce doesn't stock or the Pro 2 on this store. I don't have any other previous experiences with other grinders asides from the blade grinder. The suggested grind setting/clicks for French Press is relatively accurate, but I played with the settings every 5 clicks, 145-150 clicks after zeroing proved to be ideal for my french press (recently learned that's from the finest setting/narrowest > to courser apparently). I certainly appreciate the grind setting to be on the top, instead of having to open the catchbin to adjust, I also wondered if having a system like a torque wrench where you can pull on collar, twist to adjust, and let it go would be a better system as I found myself accidentally holding onto the grind adjuster, and accidentally adjusting the grind during grinding initially, but, I simply had to hold it lower.
The unibody (integral frame/milled from a single piece of metal) was very solid, it didn't feel cheap at all, at CAD $195 for a hand grinder, it shouldn't be. The hopper/reservoir was about 80% full when I filled it with about 17-18g of beans, but the catchbin was half empty after grinding, so you can still grind 30-35g in the hopper as they advertise, technically. Still perfectly adequate since I don't make much coffee everyday, but it grinds 17g at 25-35 seconds from my experience, though while grinding you do have to really move it around to keep the burrs fed with beans to grind. Granted they're a newer company (with some members split off from 1zpresso?), sourcing parts would be difficult, but some companies may source all from the same OEM for burrs anyways, so brand AB's model C burrs may fit the K6. I'm also unlikely to wear out the burrs anytime soon for my use case. The wooden knob had a semi rough polish, still plenty enough to grip on.
Included items: The provided mop style brush was adequate, though I feel like it thicker/tougher bristles would have been more ideal as it retained some fines. There is some provided extra gasket or seals, I have not yet used them since I've only owned it for ~3 weeks at the time of this review. I wouldn't mind paying a bit more for a storage case included as well, so I can store the handle and brush better.
Overall, it's a solid product, if you were only grinding for french press, filter, V60, you're probably better off with the Timemore Chestnut C2 at almost half the price, but I got this as something I wanted to grow into when I start making espresso, so it was either spend $100 upfront, then spend another $200 for a grinder adjustable enough, for $300 total, or spend $200 up front in the first place.
My ratings explained: 1 star: this was completely awful and I want a refund, 2 star: lacking in places, 3 star: it's as advertised, 4 star: better than expected, I would nitpick at certain things, 5 star: there is nearly no flaws, practically perfect.
