well point of view, I had a cheap set, few weeks later oxydation took place on them they became grey and the sort of chrome layer starter to come off. Rust appeared.. A rusty lock nut with 4 BBS quality nuts doesn't look good to me... after it's a choice.
Personnally I'm a thief I see good look nut's, I pass my way, I see cheap lock nut's or easy design, I'll have a try even if I damage the rims I don't care.... it comes or not.... whatever, let's give it a try..
