Interesting new flow control device from Clive Coffee. I wonder how it will compare with the Lelit, or other such devices?

The dial is snazzy.

I guess we'll soon be arguing about how strong the replacement preinfusion spring should be versus much the needle valve should open and close on one turn. Every kit seems to be a little different on those parameters.
