I like the "bling effect",
and dare I say it, the X looks a little ordinary without them... It might depend on the colour of the X though?
On the down side though, they are a pain in the @ss to clean, not functional, and what I find the most annoying is when some prick steals one of the little black plugs for his own ride... Then the running boards do look Sh!t...
But since when was anything easy owning an X...
