The filter works excellently, as I know it from my SLR camera. Since I don't have a GoPro camera, I had to make an adapter ring to attach the filter to my action camera.

The filter is much lighter than I expected. It reduces glare and reflections. It can darken the sky, but that's what polarizer filters do, it's not a problem with the filter. I experienced some glare with this lens cover that is not present with the original lens cover. I guess that's the price I pay for less glare in direct sunlight. I use it regularly.

We were allowed to test the item ND/PL filter sets in connection with Vine. The ND/PL filter sets from the K&F Concept have certainly been well received. They are also compatible with GoPro Hero11/Hero10/Hero9 Black and are waterproof. Stable and unbreakable and make a good impression for use on the cam.

I'm not a big star photographer and I use the GoPro almost exclusively for underwater shots. Here other filters are required and these are then not attached to the camera but to the housing. So thank you very much for letting me test the set of ND/PL filters. Unfortunately, not every weather situation was possible, a snow picture is still pending. I tried out the filters individually and also - in order to have a better comparison - left the subject and the light influence as the same as possible. There is a rough recommendation of the individual filter strengths for the different light intensities, but I can only recommend trying out the filters. Twilight shots look even more intense. Especially with the 64 I like to try it out. The filters are neatly packaged and protected in a well usable case. For my part, a great addition for standard use, conclusion: 5 stars

These are great filters with exceptional build quality and fit. Fits the same or better than the original GoPro clear sleeve. All 4 had good scratch resistance and hydrophobic properties. I agree with other reviewers that the polarizer strength is low, but it worked well for my purposes in removing lake surface glare while kayaking.
