Nice design (black coating comes off of course if you brake a few times as it should), no vibrations, no installation problems. The cuts are deep enough to be functional, but not so deep that you have to worry about compromising structural integrity. I've ridden them for over 700 miles (EBC Redstuff pads) and they stopped smoothly at any speed, no obvious noise, no fading. Braking power is very good. I can't say 5 stars until I've driven it a few thousand miles as that would be unfair. Dust doesn't seem to be a problem when installing the rotor and pads. In the short time I have traveled with them I would buy them again.
