Anyone with HID installed in factory housing?

I'm looking into purchasing a HID kit from autolamps-online.com. Friend of mine put their 6000k kit in his 2002 passat. He's got projectors so his look bad ass. I have regular reflective lenses and I'm concerned that the beam pattern from the HID kit would be all over the place, anoying drivers. Anyone with experience please reply. :smoker2:
