Bests & Worsts Reviews from Amazon

I purchased a Joby sling in August ahead of photographing a wedding. It functioned well for the duration of the day, but last night when I relied on it for an outdoor event, the strap failed miserably. The resulting failure sent my Canon 7D and lens falling about 3 feet onto a concrete sidewalk, breaking the lens hood and filter and seriously dinging the body of my camera and lens. This happened not even 30 steps from exiting my car and after I had checked the screw at home to ensure it was still tightly attached. It worked loose very, very fast. I'll be taking it to a local camera shop to have it examined and determine if there is any internal damage to the body or lens. I've had the body since 2010 and the camera was babied, cleaned and handled with the utmost care, so this is unbelievably upsetting. Prior to this sling, I avoided straps and slings primarily because I did not want to trust $3,000 worth of photography equipment to a cheap piece of nylon. I had read good things about the Joby sling prior to my purchase but now I simply cannot recommend it to others. NOTES: -I've been photographing at a semi-professional level for 8 years. -Prior to my mishap yesterday, I cleaned my lens and re-tightened the strap. It came loose and detached within not even 30 steps of leaving my car. -The strap was attached to the 7D directly, not a battery grip or anything else.
