It depends if you want to kill your camera. I wouldn't trust the bags, particularly the cheap ones. Fairly reliable ones might work, but they are harder to reliably test since they rely on zippers and velcro rather than o-rings and pressure seals. They are more designed more to protect against surface usage where the camera may get splashed or fall on the surface of the water. They are specifically not designed for going deeper than 15 feet (about 4 meters) and even that depth is often sketchy.
The one you linked to sounds pretty reliable overall, but I'd still be a bit nervous trusting a DSLR to it for going 10 meters down as it isn't designed to go nearly that deep. (And even if it does work right, it still is going to impact image quality significantly and be difficult to use since it isn't custom fit.)
Your better option for your use case is to get a waterproof point and shoot.
