The first time we used this strap, I lent it to my (adult) son to take photos with my brand new £300 underwater camera when we were snorkelling with manta rays in Hawaii. Unfortunately, my son didn't notice at the time but the narrow cord attaching the camera to the strap seems to have snapped as he climbed up the ladder onto the boat and we lost not only the camera but what I understand were some amazing manta ray shots. (Scuba divers were unable to retrieve the camera.) My feeling therefore is that the cord on this strap needs to be stronger.
