Nice bit of kit imo, simple and unobtrusive. Fitted it myself and set it up to start with, then had it tweaked by the guy who mapped the car (he uses them all the time so had his preferred way of setting it). Simple wiring, has it's own harness that you connect to the solenoid and two pipes to the solenoid from actuator and compresser housing, couldn't be easier! Seen those gizmo controllers, they obviously do the job too though the ones i've seen do look a bit cheap and tacky imo (not that it's got anything to do with how good they are mind lol).
