This is a "Freewell ND filter" for GoPro HERO. It's compatible with GoPro HERO 9-12, and I used it on my GoPro HERO 12. I used it for about 3 months, and the frequency of use was low. It has never been used in the rain or subjected to any impacts. There are no noticeable scratches or stains on the filter itself, but please understand that this is a used item.
