I was hesitant to buy this type of product since I heard that the BlackRapid one would come undone unexpectedly causing their camera to fall (!!) but for the price I thought I would try it! However, I used it with the OP/Tech sling and tied one of the two straps to the screw and one to the regular camera strap hooks on my camera - failsafe! So this way my camera doesn't twirl by my side and unscrew. Works well so far but you have to unscrew it if you want to set your camera down on a tabletop, etc.
