I bought a first release VF-0S from mwf member, moose. No locking feet mechanism but it's still great. No exploding shoulders or even a stress mark. My DYRL VF-1S Roy with Super/strike and the rest of my V2 do not have any problems with shoulder hinge. Only yammie crap I found was the 1/48 VF-1S Hikaru 2nd release, both hip intake cracked and some parts of it broke while I was bringing down the legs. I've glued it back, transformed again recently to have it's right hip intake broke into 2 again. More patients and super glue fixed the leg for now.. (It's in Urban Camo GBP now)
