I used this with a GoPro9. Being able to go wide-angle really expands the range of uses, and it was the right replacement part to buy. As it's a lens, I used and stored it carefully, so there are no scratches or dust on the lens. There are also no scratches on the sides. I am also listing other GoPro products at the same time, so if you purchase them together, please let me know and I will consider the price.
