Review on Artman Housing Case Compatible with GoPro Hero 7 Black, Hero 6 Black, Hero 5 Black, and Hero 2018 - Waterproof Diving Protective Housing Shell with 3 Pack Filter + 24 Anti-Fog Inserts + Bracket Accessories by Cedric Ford

Several times a year I snorkel and look for a blue mist filter. I was delighted to find this product that not only gives you three filters for less than the cost of an official accessory filter, but also offers an extra level of impregnation. The My Hero 5 Black fits like a glove and feels solid. As an added bonus, two thumbscrews were included with my kit (although they aren't listed in the product description, according to YMMV). one with a standard handle and the other with wings that make it easy to turn with wet or cold hands. A pleasant surprise. I will try to update this review with before and after photos after my next snorkeling adventure.
