Well, "cheap" can mean a lot of things. I wouldn't stay away from something just because it's inexpensive... I bought a BMS clutch stop for $5, and everybody thinks that it's a great mod (and it helps that BMS makes stuff almost exclusively for our cars).
But of course, if you mean "cheap" as in "low-quality", then I agree that I shouldn't put it on my 1er. Still, I'm not put off by the cosmetics of their product or their workshop... but if anybody has negative feedback about their product itself (i.e. didn't fit properly, wasn't as strong as advertised, etc.), then I'll stay away from them.
