But is it even tightened, it also holds. About wear on the locking screw, I can not say much because I'll disappear the bracket without collapsing in the closet, as it is not needed. What "for life" it is not for certain though. "On past life" is also the color coding, the one based on the size of their own hands aims to provide a optimum mounting angle ... There are too many notebook series and too many preferences.
