I purchased this for my Delta Platinum Contractor's Saw with Unifence.  Installation is pretty straight-forward, although I have to modified my Rockler outfeed table a bit to accommodate one of the mounting brackets.  Once installed, the blade guard works very well.  I particularly like the easily-removable splitter -- very handy when I am using my sliding table.  My only gripe is that I wish there is a vacuum port in the blade guard.  The saw dusts seem to be focused to fly directly back at you -- I guess that is a good reminder not to stand directly inline with the blade!
