If it is not as described then there are actions you can take. Yes, buyer has to beware, pretty standard.
If people have ever had issue with anything I've sold i tell them to send it back to me and I'll refund the $.
I've never had a return. Sometimes people want something for nothing, but that's another story.

I do like to keep things original that deserve to be original unless there is a good reason for a swap, like fitment, breakage, bendage, smashage.
