Can't fault them one bit, they done about 6k on teh pads they come supplied with then I changed to DS2500 and they are still lasting well, still on the original rotors too !
The braking is far better than any other setup I have used and there a damn site cheaper than a full AP setup but I think they are easily as good.
I'm gonna change to rear discs though with bias so I can really get the braking perfect.
They also have very little pedal travel which is something my old v6 setup gave loads of which was horrible.
