This forum, and in fact life, would be pretty dull if nobody expressed an opinion. If nobody here has fitted one of these spoilers you end up with either no replies or some opinions. Ergo Sootpigs post is a waste of time as he offered an opinion too. This is a good forum with a lot of very helpful members. In my opinion of course.
It's a fairly pricey item to take a chance on regarding fitment, quality etc. Also I can't see a cut-out for the high level brake light in the photos.
Personally I'd buy a genuine VW one as it's a little cheaper and is a guaranteed fit. Only thing is you'll have to get it painted. Or you could carbon wrap it to achieve the same look if that's what you want to achieve.
