Comments on the quality and reliability of an OBX LSD? Thanks.

 

Is this the one ? If so all the reviews n vids I've seen there's been no complaints. From what I've gotten its almost just like a more expensive one though I can't think of brand name off hand.. if so, I'm curious too about any 1st hand accounts as this is coming next for me with a light weight flywheel n stage2 clutch after my head n cam..
