Anyone else receive their grinder yet? According to the last update on 9/4 they had arrived in the U.S. & would be shipping the end of the following week. That never happened so I asked Kerry Adams when we might be seeing them & was told that they will now start shipping from Rochester, N.Y. on 9/28. We'll see.

I live in Singapore, and received my ROK grinder a couple of days ago. Finally got to try it this morning to make a V60 pourover. A few thoughts:
1) beautiful looking machine. Base is super sticky as advertised. This thing WILL NOT move while you're grinding.
2) disappointing burr alignment. I dialed it open 1 full rotation and cranked the arm, watching the gap between the burrs widen and narrow.
3) after a test grind, was fairly impressed with the apparent grind uniformity. It definitely looked pretty darn good to the naked eye.
4) today's brew only proved point 2 above. Layer of fines mud sitting on top of my V60 bed after brewing.
5) static build up is annoying, but their to tip to sprinkle water in the beans before grinding works.
6) the way the infinite adjustment dial sits below the burrs means that there's a lot of grinds that that don't make it to the container. Clean up therefore becomes messy.
7) bean hopper is a bit shallow, which means that partially ground bean bits will pop out towards the end of the grind. Similar problem in the older Harios before they started including that cap. I need to dig out that old Pringles cap I used to use for the Hario and see if I can use it for the ROK.
I also own 3 other hand grinders: Hario Skerton (with a 3D-printed add on to try to stabilise the shaft near the burr), a Porlex Mini that I bring to the office, and a Portaspresso Rosco Mini.
The spring mechanism used to hold the conical burr in place reminds me of the Porlex, and the resultant fines is very similar. However, I still feel there is better grind consistency than the Porlex. Absolutely no comparison against the Rosco.
I guess for the price paid, I shouldn't have expected Rosco quality... That having been said, it IS a lot easier to grind, compared to the cylindrical grinders that I own. Will need to start tinkering this weekend to see if I can stabilise the drive shaft better and reduce the wobble (a la Hario?).

I had almost the same exact evaluation, the static was crazy bad on some beans without water drops in the beans.
What about the grind adjust wheel, have you noticed that as you grind the adjustment drifts or changes? There is no way to lock the grind size setting in place, the little wheel just unthreads down the shaft. I tried both setups, the infinite adjustable and the click setting, both have drift during grinding. I am waiting for the rest of the USA grinders to arrive, hoping someone here finds a hack to resolve this.

Have you contacted ROK about the adjustment issue?

John,
No, really that is on me, but I have until just this week been ridiculously busy at work. I need to get an email in to them and ask about it. I kept thinking I would pop in here and see everyone writing up their own findings. I didn't realize how much earlier those of us in Asia were getting deliveries. Hope the USA shipments get there soon.

Will need to check to see if there was any drift on the adjustment wheel. In my mind, the only other way is to unscrew the infinite setting washer and make it click-set again (which should stop any drift). Will play around this weekend and see if I see anything and report back.Bak Ta Lo wrote:I had almost the same exact evaluation, the static was crazy bad on some beans without water drops in the beans.

(Going to now figure out how to make this a new thread on user/owner impressions...)

Well this really isn't the kind of feedback I was hoping to read I was hoping from the specs that this thing would be a decent step up (in terms of grind quality) from my capresso infinity for espresso. I've been making do with it for a few years now and gotten my technique (and espresso machine) down to the point where the grinder really is the only thing holding me back. Now I'm starting to wish I had just gone with a used MDF or something similar. Unless the burr wobble is more of an issue with the larger grind settings (for pour-over / press). Anyone used this for espresso yet?

Once again the latest update says that the U.S. grinders will be shipping next week.

Today's update isn't going to make supporters waiting for their ceramic burrs very happy. Evidently they are performing poorly so ROK is dropping them. Anyone that bought them gets a voucher for a replacement set of steel burrs?? Since they can't supply one of the advertised perks I would think that offering buyers their money back would have been a better idea.
I did finally receive an "order processing" email from WLL yesterday so hopefully my grinder will ship today.

Good luck, man. I'm really amazed that they're having such difficulty fulfilling orders in North America and Europe. Look forward to seeing more reviews online once they start getting on people's kitchen counters!
