Just wondering if anyone had any experience or thoughts on this "High Flow 6 Hole Group Head Screen Diffuser Screw" from voltage coffee.

https://www.voltagerestaurantsupply.com ... cco-slayer

in product page it lists:

> Designed to maximize flow and even the water distribution across the shower screen

> M6 stainless steel 6-Hole high flow diffuser screen screw that works with all commercial and prosumer La Marcocco, Slayer, Synesso, Mavam and Modbar machines

> This is a great upgrade for the home user trying to squeeze every bit of performance out of their Linea Mini, Linea Micra, GS3, Slayer 1gr, etc...

> The main feed port was enlarged 18% to maximize water flow to each of the 6 holes

> Unlike the factory 4 hole screw, every hole on the Voltage 6 hole diffuser screw has been chamfered to remove sharp edges in effort to produce a symmetrical sloping edge that maximizes water flow

> The size of the screwdriver slot has been minimized to reduce the amount of coffee residue that can be collected over time

For water distribution improvements, you'll have to check it out and report back. In terms of changing the water debit, I don't see it; since it most of the flow resistance ahead of the puck is in the gicleur, not the diffuser screw.

Seems like a gimmick to me. Especially on the Slayer with the needle valve. And I challenge people to be able to repeatable enough shots to tell the difference on these machines. So many factors come into play just shot to shot including drinking temp that I doubt one can really tell the difference.
