Purchased a few years ago and is unused. FitStill Waterproof Housing This is a third-party GoPro waterproof housing. It's compatible with depths of 40m to 60m. The build quality is very solid, and it features a double-lock design not found in other housings. In terms of robustness, it's in no way inferior to the genuine product. However, some users may find the buttons a bit difficult to press. It's thicker than other products, but its lightweight design is also highly rated. #GoPro #WaterproofCamera #Underwater #UnderwaterCamera
