We used this for snorkeling & tubing down a river. It does NOT leak at all & keeps your camera 100% dry. We swaped out the leash for the one that came on the alligator wallet (same manufacturer) cause it has a sliding thing that you can tighten up, allowing you to hang around your neck & not float off. I will say though that none of the picks we took under water while snorkeling came out. It's very difficult to see the screen on your camera to aim for the pic because the pak it like a bubble w/ light reflecting off it. To take under water pic's you really need a waterproof camera. This did work great though for our tubing excursion where you are taking pic's out of the water. It's a great product for "above" water use. :)
