Ah, Weber is using "randomizes" to describe the action of their tool on the coffee particles in the bed, not the tool itself.

I will not get into a stochastic process discussion, but I'd say yes, their tool, this tool - and any and every tool from a paper clip on up - "randomizes" the coffee particles in the bed.

If it is lack of concentric orbits, then Weber may be just taking a shot at the Barista Hustle and Duomo tools.

Worse was DF64, that thing was awful, worse than all my grinders combined for static mess with no rdt

The beans were out of the freezer and exposed to air long enough for condensation to form on the surface of the beans. (The condensation may not be visible to the naked eye.)

I RDT all the time as well, but I usually keep roasted coffee in my refrigerator.

That was my interpretation on it as well. However, Barista Hustle's tool implemented faster spin by design and it kicks up the grinds in the process which does create some level of randomizing. Only downside (in my view) of their tool is the price. I suspect that Etsy may come up with their version of such tool for 1/4 of price...

What's the consensus on speed/# of rotations?

I'm seeing a little bit of a divot develop in the middle - maybe I'm spinning too fast?

I don't know about a consensus, but I'm down to 20 RPM now - with v4.

I have posted my comments on the latest iteration of the coffeetoolsca device here at #111...

After using for a while, would you buy it again? It is laughable what I am using, basically and oversized safety pin. But I am not entirely opposed to spending some money to get consistent results.

Yes, I would buy it again. It is a quality tool, and the feel with the v4 is great. The customer service from DH Nu has been excellent. I also inevitably buy any coffee stuff that is made locally.

But ...

I use machines that take various 49mm baskets more than half the time. I often use single baskets. Thus, the CoffeeToolsCA tool doesn't get near as much use with me as it would with someone who uses the same basket most of the time.

Is the CoffeeToolsCA better/more consistent than a Levercraft tool or the many copies(*) of the Levercraft tool? Hard to say, as how well the Levercraft tool works depends on the person, and I have used the Levercraft tool for a long time. It is kind of like tampers. Plenty of people like auto-levelling tampers and those tampers seem to help those people make more consistent coffee, but an auto-levelling tamper wouldn't do anything for me.

* for price/performance, the JKimMakes tool sold by Appamakes (JKim's father) on Etsy is hard to beat ... and there is always pins stuck in a cork.

Thanks so much for the insights. I have a lsm group so all my baskets are <55mm. He's one of the few that seem to offer that size

Okay - I have had the 55mm version for about a week. Still getting used to adding this to the workflow but I have to say that whatever I was doing before was inadequate. Since using this item my grinds are all uniformly fluffy pre-tamp and it has significantly reduced my channeling. Still playing around with pin depth as I have a couple different basket options between a deep 21g and shallower 18g. I have been currently using a dark roast 16.7g (saka) which tends to sit high in my baskets.

I would call this a win but it's early. Will see how it is after using it for a month or two and update.

Thanks, Mike
