SANDMARC Cinema CPL (Polarizer) Filter for GoPro Hero 12, 11, 10 & 9 Cameras

It’s a good product

I haven’t had my GoPro 10 long but I like the effects that this easy to use lens has on sunny days! Good product!

This item does not fit on the lenses of the GoPro Hero 13. All of the GoPro accessories are the same size between 12 and 13 and this was advertised as being compatible with the Hero 12. It does not fit over the lens. Poor quality also

Awesome, robust variable ND filter for the gopro!

I use this one in the house. Little worried about it popping off. It's on pretty good though. Money versus paranoia

I always thought I was using it incorrectly. I could never get it to seal or fit properly. It's too old of an order for support but poor quality control on my unit. Was excited to use but felt too scared to use and tried to make it work.

Super cool filter, amazing for intense light or light transition. I recommend it.

Awesome! Gone are the days of useless footage and changing lenses all the time. When paired with the GoPro quick app, your shot will always be primed. Although it works with the media mod, I wouldn’t run around with it or anything. Also, keep your ISO max/min the same, or else moving shots won’t look good. You’ll get weird flares on the left and right side of the screen. Also, it doesn’t work with the hero 11 8/7 mode, you can see the corners of the lense on your footage.
