The cable is now about 5 months in use, and the side with the latch is (almost every day) deducted from me often of notebook and plugged again. The plug feels high-quality and the silver is obviously metal (aluminum?). The cable is extremely flexible and the TOSLINK connector on the other side is firmly seated in the socket (which unfortunately can not be said of all optical cables). Useful is also the dust hanging on the cable and can therefore always easy plugged as long as the plug is not plugged in.
From me, saying an absolute buy recommendation and 5 star.
