Has Anyone Installed One of These Roof Spoilers?

I went for the $45 eBay flexible unpainted spoiler. Because of the black accents on the liftgate I thought it matched perfectly with the styling, however painted looks just as great! As with "Ragz" I also mounted the spoiler at the top of the liftgate, I believe it flows better with the roof line at the liftgate retaining functionality of the washer nozzle. If I would change or do anything different, maybe black vinyl wrap for the panel its mounted.

20 min install, most of the time spent in prepping the surface and marking positioning.
