Any one try the 5 blade Ron Hill props seen on ebay? Is it a copy of a high five, maximus or what?

I purchased (2) from R Hill for OB CC boat, he took my money in 2 seconds then it took months to get the props. Props are low priced low quality and very thin. Props ran ok, not any better of faster than othe prop combo's I tried. I would not purchase from them again however
