I got this exact one as well. I'm a little reserved on how it'll look since I think it'll either look considerably cooler or unnecessarily worse than the "M5 style spoiler". It has an aggressive raise in the middle which will be a make or breaker for it.
For $75 it's a damn good deal. I hope I like that twisted-raised middle part as it is more unique than the M5 style (not to say you see M5 spoilers everywhere, so any spoiler on an F10 is pretty unique).
