Yes the amount of knock of EBC product on the market nearly put them out of business. I have one of the main distributors a mile from my house and they were telling me recently that they are still getting customers showing them samples. The problem was who ever was making it used poor quality pads just painted in the various colors they sell. Probably not a problem on a car rarely driven hard but if you bought pads to upgrade your braking system because of engine upgrades or you drive hard potentialy lethal. The biggest problem was I understand was material coming away from the the backing plate and poor performance.
Personally I find EBC products work well.
