Logan Curtiswrote a review of GoPro Floaty Backdoor on April 9, 2012
I was a little skeptical at first as to if it would really float it as well as they say, so I turned on the jets full blast in my hot tub and threw it in. It stayed on top. It would get pushed down pretty hard, and popped back up every time. Works. Well worth it, definitely gonna be on my cam any time I'm on the water.
