Few know about this handy little accessory. If you're lucky enough to have a camera with SDI connectors, these might not be as necessary, but for those of us who mainly shoot DSLRs/camcorders that use HDMI, audio jacks, and remote control ports that don't screw/latch on , it's easy to pull the cable out of the connector and in my case the connector on the camera breaks because of pulling in the wrong direction which bends the connector. Once the connector on the camera is broken, it is useless.
