The bushings appear to be good quality, but the adapter plate absolutely would not fit on my router base.  I have a Freud FT1700VCE (listed as being compatible) and I tried the plate on both my fixed and plunge router bases with no luck.  (I even dug out my manual to make sure that I was trying to install it correctly.)  It looks like they machined the plate just a bit to big to fit in the base.  I probably could have ground down the outer rim of the adapter a bit, but I would have expected more from Freud.  Returned.
