Just thought I would add my experience with this guy. Years ago, I was looking into building or buying a pack, and while looking around, I stumbled onto this guy claiming his shell was cast from the movie molds. Sounded interesting, so I messaged him via Facebook messenger and told him I was keeping him on my list of options, and (only really being interested in the shell) if I were to buy a completed pack would I be able to "upgrade" it later myself with parts from the community if I chose to. In the mean time, I did more browsing the build section of the forum and noticed he was blacklisted, and read up on his "screen used" shell. Needless to say, I completely ruled him out as an option, and decided it would be better to just build my own anyway.
A couple of months later, I finally got a reply. A very blunt "The parts are not removable." Something I knew was untrue at that point, because I knew he was simply gluing the thing together. Even if I hadn't been turned off by the forum, I definitely would have been put off by his less than cordial attitude towards a potential customer. Which, I surmise, was based on the fact that I would even suggest buying upgrade parts from the GBF community.
On a related note, I noticed in one of his more recent videos, he insinuates ANOVOS has recast his stuff for their kit.
