Inexpensive and well thought-out mount for your camera or GoPro. Perfect grips and very ergonomic. The materials on the screws and threads should be stainless steel or brass with a nickel or chrome plating, but that is not the case, ordinary steel. As a result, they will rust immediately upon contact with seawater, even if they have been thoroughly rinsed in fresh water and dried. These minor material corrections need to be made in order for this product to last beyond a few dives.
