Got the G80-1851LPMDE in the mail yesterday, and I'm disappointed. Seller claimed the keyboard was barely used, and in very good shape... True story, bro. Reality: yellowed case, shabby logo, cracked corner and the case came opened, I'm unable to close it. Beige keycaps feel smooth more like POM than PBT.
The only good thing is that black switches feel very light there, much lighter than blacks on my G80-1000HAD interestingly enough.
