Since they are so rare in the wild, I wondered if anyone has tried this flat burr hand grinder:

I'd love a high quality flat burr hand grinder but I don't think that's it...

They lost me at "EASY AND EFFORTLESS GRINDING WITH THE THREE-STAGE EXTENDED SWING ARM"

With that price you probably better off with one that has known people in the industry involved like the Pietro and that has a orientation of burrs that rationally make sense for a flatburr hand grinder.

That on top is also made by an actual grinder company with necessary know how.

The Pietro is by far the best implementation I seen of flat over the years, there still a few quirks needed fixing but at least it actually make sense.

Yes its really annoying, an Italian thing the LM home is equally if not even more maddening. Trying to order or look at Micra and I was turning half mad before I came to the purchase site.

In case anyone is adventurous and would like to test it with lower financial risk, this grinder is currently $107. Only 3 steps suitable for espresso, so probably not easy to really dial in, but might work for pour over. There are very few reviews even in the Chinese coffee world. I have seen people saying that this takes forever to grind but not too cumbersome due to the slow feed rate.

Here's a review:
Didn't realize it has a pre-breaker, kind of nifty :o
Seems the ghost burr option makes more sense though considering the seemingly long grind time and effort for espresso.

I ordered the identical one off TaoBao for around $100 a few days ago. It's with my shipping forwarder now, and will drop a mini review when I get it.

At worst, it's $100 for a paperweight, which I can live with. At best, it's a highly unimodal ghost burr hand grinder which will supplement my espresso bar for when I want filter coffee.

For me, the point of this is to be purely filter focused - I wouldn't touch espresso with this with a ten foot pole.

This recent HB topic spurred my initial look into it, together with Sprometheus' recent video.
