AAP01 folding Thumb Rest - Silver (Left side )

Nice piece of kit. You have to screw it on very tightly to stop it from moving under pressure so I was a little worried about rounding the edged tho that hasn't happened as of yet. Not sure what the point of the folding is, as its on a spring retention so it just flips straight back to how it is in the picture, although with that said maybe I'm missing something.
