Summary: I bought this strap to offset the weight of my Lowepro Zoom-I camera bag when hiking or carrying it for extended times. While the strap helps, the bag is not stable with just the waist belt; I still needed to use the shoulder strap to keep the bag from flipping over. I still found it helpful as the the two straps together prevented my bag from swinging around while hiking.
Summary: I bought one of these and used it one time. The design of the buckles allows the belt webbing to slip and loosen the belt just by normal movement. Much better to get a standard 2" web belt with nylon buckles.
Summary: I couldn't find this item until I happened to look on your site. Not only did you have it but at the best price anywhere including shipping. It came within one week and arrrived exactly as described. I will be ordering from you in the future.
