The bike and other mounts are useless, the picture was unwatchable and the unit picked up every vibration making the sound something awful and screechy. And I was on smooth concrete the entire way.Underwater the picture is good from 3-5 feet, that's it. The sound is still a mess, since it seems to rely on vibrations, and even the water overwhelmed it, every dunk was thunder.Overall, a piece of junk barely worth $30, if that. I bought mine FOR water, so I can still use it, but I should've researched it better.
