I bought some about a year ago. here are my thoughts
The halos and leds look sweet as driving lights
The bluish tint of the projectors works great in snowstorms and rainstorms.
The normal style (brights) are very brights
The projectors are actually not that bright in normal driving conditions. I actually added some hella driving lights behind my grille because i wasnt satisfied with the light given off from the projectors. Maybe I'm just a light freak though. Lots of deer and elk around here.
The ones I got off ebay required wiring some things up. (splicing, twisting, soldering) such as the halos and leds. I actually did a custom job and made the leds and halos always be on, which isnt necessary. But for the most part, it is a plug and play install. The only other thing that was somewhat difficult was aligning the lights so they shine straight. Just use your stock lights as a guide though and that will go smoother.
Hope this helps, all in all im very happy with them!!
