Review on Nechkitter Waterproof Replacement Protective Accessory by David Fisher

I used it as a waterproof case for my GoPro while snorkeling. My maximum depth was 100 feet. After a few dives, a small amount of moisture entered the hull and condensed inside, blocking visibility. I lubricated the gasket with some silicone grease and that seemed to help. Another issue is that the button on the back of the case stops working below 30 feet. The button wasn't pressed, so I couldn't turn on the Go Pro. I suspect it was caused by stress in the case. When the camera was over 30ft I was able to drop below 30ft and continue shooting with the top button which still worked, but the Go Pro tends to shut down fairly quickly so this wasn't a practical workaround.
