Review on Suptig Rechargeable Waterproof Housing for GoPro Hero 4/3+ Underwater Action Camera - Water Resistant up to 131ft by Benjamin Saric

I used it to mount my camera to the rail of a boat on the Shannon River in Ireland to capture daytime time lapses. I used some 10ft USB extenders which I taped around so I could connect to the boat's power supply. It worked so well I bought a second one and use both with backup batteries for kayaking and other activities where I need longer battery life. Although I've never fully submerged the case in water, I can say that it performs well in a downpour with strong winds.
