It's the perfect strap to hang the camera. Elastic and adjustable, it is easy to set. Personally, we added a thin nylon rope long enough to connect the camera to the wrist by security, because by dint of plunging high enough, she had slipped and was almost lost. Hence the safety cord. With regard to the housing, it is perfectly sealed and at the image, one sees no difference. With this case - and manual operation - we can only initiate and pause with the button in case of ass. You can not change functions without removing the camera. The camera was already comes with a waterproof, but no strap, suddenly now we have two boxes.
