I don't know about that particular seller, but I got my ///M-Sport pedals on EBay. I'm sure they're
completely fake...
Anyway, here's the thread from when I installed them in my X3:

If you like those ACS pedals, I'd go ahead and buy them. On an item like that, it's not too bad getting them from EBay, because there's no moving parts/electronics in them. Just a slab of metal with some logos and a rubber backing. Good luck!
