Emerson stuff if pretty junky from my experience with their products. But for $40 it may be a good deal. Im sure it does not cost much to make a gopro camera in china or wherever, so maybe Emerson is trying to take a good sized chunk of the Gopro market.
Buy it, try it, and if you dont like it, return it.
Edit: Just did some reading on this and its 720p and is basically a stripped down cheesy version of the Gopro with less features. It is water resistant/proof. The video sample I watched on youtube looked terrible and had NO stabilization software that I could see with my naked eyes..lol Bounce up and down all over the place.
Makes me glad im getting a Gopro3 white edition for a early Christmas present.
