To use it, simply remove the B-Grip Plate on the B-Grip Holder and replace it with the red mat on the strap. The clever flip out platform allows you to place your camera and lens on a table without either touching the surface. The value of the hand strap is functionality. Having your camera right in your hand means you're always in shooting position. It also provides an additional measure of security since the camera is held firmly in your hand and not dangling from a strap.
