Got a bit of info on the seats.Don't know a thing about any "chinese knockoffs" but can tell you I had to wait 7 months to get mine from Millenium because they had returned a bunch of seats to China because of quality control problems.I waited so long to get them they were embarrassed and gave me free shipping and knocked a bunch off the price.Sold in USA,made in China.At least that is what Millenium told me over the phone.........
