なおまま 5 I'm using it on a GoPro Hero 7 Black with a case, because it was the cheapest I could find when I bought it. I didn't see many Hero 7 wind covers either. So I wasn't expecting it to fit perfectly, and it doesn't. But it works well enough that I don't mind. Some of the cutouts don't match up exactly with the button on the Hero 7 but it's not an issue for blocking wind, which is the main reason I got it. The main issue I had was how poorly it was packed for shipping. It arrived super warped and flat. It took a while of leaving it on the GoPro for it to retain its shape.Overall it does its job. If I eventually need a replacement and there are still no other option I'll buy it again.
