If you see what looks like a wavy, bent, or crushed washer at section joins on your USB FaroArm, do not be alarmed. This wave washer is correctly installed. The wave in the washer is preferred to better cushion the join. This is done deliberately on some but not all section joins to ensure the performance of your FaroArm.
Wave washers are installed like this on all models of USB FaroArm, but are most visible on the FaroArm Edge.
