Rotorworks brake rotors?

Does anyone have experience with the Rotoroworks brake rotors from WS6store.com? Front and back rotors for 170 is a real good deal and im just making sure it isnt too good to be true.

Anyone?

yes, i have them on my camaro and have been pleased with them so far. seemed to help alot with brake fade, and i had the camaro sitting outside for 4 months without even starting it and there is no rust or pulsation whatso ever. i'll definitly buy them again.
