Anyone ever use one of these? I recently received one of these as a gift. I had never heard of them before. There is a waterproof case made for them and since the cost was zero$$ I could justify buying one. I like some of the function but clearly, it's not what I was ever thinking of. Still, if it would work..................2 hours recording time before needing to download would be OK. Charging through a USB port should be OK. Not the unit to take on a trip but maybe a day paddle? I don't know. The waterproof case doesn't look like it has any means to screw into a camera mount and I think it only orients in one direction, still........it was free and maybe someone has some experience with one on the water? Anyone?
