Just got mine 2 weeks ago before a Hawaii trip. Waterproof works fine, but one prob I encountered was behavior when moving camera from above water to underwater. I was trying to film my 4yo daughter swimming in the pool, would start the recording above, then when I would go underwater the water pressure somehow pressed either the back and/or task manager buttons, which ended up stopping the recording about 95% of the time. I ended up going back to my GoPro. So, from my experience, a great waterproof case but don't plan on doing much (or any) underwater recording with it.
