The go-to valve for precise boost control
It works really good and I prefer these over a three-port because you can run a really soft wastegate spring and control your boost from nothing all the way to max output of the turbo

Direct replacement for my HAAS mill valve
My HAAS VF4SS mill developed an issue where it would randomly get an alarm about problems with the tool changer pocket and stop right in the middle of a job. I tracked it down to an air valve that was not fully activating. Looked on HAAS website and the valve is $155. Ok, that's not too bad. Just did a quick search on Amazon and the same valve popped up for less than $50. It arrived the next day and I installed it. Installation was straight forward and without drama. It's been a week since the installation and not one error yet vs one or two per day previously.

Exactly the same as the Turbosmart valve for 1/2 the price.
Works great so far.

Looks good
Looks like a genuine Mac 4 port valve. Only giving it 4 stars though because it came with no fittings and all the other kits I see include them.
