I've only had this product for a few days but so far I have found these headlight assembly's for my 2003 Passat to be of good quality and virtually indistinguishable from the originals being replaced. They really look great. These were purchased to replace the originals that had become yellow and "foggy" in appearance and they definitely make my car look much better while also greatly improving the light emitted from my headlamps.
It it worth noting that these headlight assembly's are not all that easy to install unless you are pretty handy with tools, etc., so you may want to consider a body shop for installation. It took me about 2 hours to replace both the left and right assembly's on my own. Space is very, very tight when you are installing these so you must be patient and don't try to force anything or you will snap/break parts of the assembly.
All and all I would recommend these to anyone trying to improve the appearance of their cars and/or the light output of their headlights.
