Don’t buy from MBoards. There is absolutely 0 support even on social media, and my package only got shipped when I filed a complaint to my bank (ironically, I was trying to contact him to cancel it). He fought the claim and sent picture proof that he sent the package after I wrote the complaint while claiming he had sent it before.
He’s in college, being young doesn’t really excuse this many issues. I’ve bought parts from high school kids without issue. He just needs to admit he can’t run it very well and stop, or start shipping out items properly. I haven’t seen anybody buy from him and not get screwed over.
