I do the initial bloom/swirl like normal then just put this on top and fill it with water a couple of times. I'm using the Timemore one which fits perfectly over the top of a Kalita Wave or probably an aeropress but sits partially inside a regular v60 so if the grind is too fine and it drains too slow then the water touches the dripper, not that it seems to make any difference to the coffee coming out. It fits about 250ml of water inside.
I hadn't even known that was a thing, seems like a cool idea!
I like the idea of having a bit more control over the agitation going on, though it doesn't look like it has that much capacity so would need frequent top ups. How do you end up using it (in terms of number/frequency of pours)?
