am very satisfied with the quality of these filters! They rotate on and off my GoPro HERO10 Black lens very smoothly and securely. They are very comparable to the regular models my camera came with — same dimensions, weight, and clarity. I've spent most of my time using the polarizing filter from the set so far and it works great! I'm still a beginner but I can really see a difference in surface reflections in my photos. One thing to note is that I can't wear my GoPro's protective silicone case while using this particular filter, as the case extends to the edge of the case, covering access to the dial that you rotate to set the polarization. The four filters are supplied in a plastic case firmly fixed in foam. I found this very reliable and protective when taking them with me on trips because I could keep them in my backpack with no worries. All around very satisfied!

was happy to find this filter set for the GoPro 11 with its 3 different ND filters and a circular polarizer that actually rotates to get the best effect. It really isn't CPL in my book without the rotation feature, so I was glad this tiny CPL filter had that capability and was easy to adjust. I have a “mini” version but the filters fit both the mini and standard sized GoPro 11. The fit is identical to the original GoPro filter that comes pre-installed on the camera. Admittedly, I had to look for a way to remove the filter as I didn't want to break my new camera, but it turns out it's a simple twist of the filter 90 degrees to remove it. It requires a little strength, but that's better than being loose. The filters go back the same way, just pay attention to the two metal rods. It's obvious how to line them up once you see the clamp holding them. A set of ND filters can really open up some creative options, e.g. B. longer exposure times. A polarizing filter is a great way to remove reflections off water and glass, and to darken the sky for better color saturation. The construction of the filters themselves appears to be premium and feels premium. This filter set comes in a simple but very nice case that keeps all four filters safe. The box is about the same size as a regular single filter housing and doesn't take up much extra room in the camera bag. So where the GoPro is going, this filter set will go.

had to wait for the new Raplecement Gopro to test these ND filters and I must say that the K&F Concept company has improved the quality of their products. Filters feels premium and looks premium. They fit perfectly on my Gopro 11, same goes for 9 and 10. I chose a standard daypack because I mostly fly FPV drones with GoPro.

had actually used the K&F Concept ND filters for my DJI drones and GoPro for years and was always satisfied with them. Now I have received this from K&F for testing my new GoPro. Delivery was quick thanks to Amazon. The filters fit my old GoPro 10 and also my 11s. The filters from K&F Concept too, of course. There is not much difference in price between the two sets. K&F are about 5EUR cheaper. The filters are well made and sit firmly on the camera body. Even with a lot of action and turbulent scenes, there is no need to worry. The filters remain reliably in place. The exposure time is lengthened by the ND filters and the pictures simply look much better than without them. There are some good apps that recommend certain ND filters depending on location, time of year and position of the sun/time. Lens flares in backlit shots are also largely suppressed. The lenses are easy to clean and a case is included for transport. I can only recommend. I will use these ND filters for the GoPro 11 and my son will then get the GoPro 10 with the K&F Concept filters. :) How come? Because in detail, the K&F are a little better, especially with backlighting in the sun. But only minimally.

K&F Concept is a permanent guest with me, whether for my cameras or the GoPro. You can always use ND/PL filters anyway and in this quality anyway. The filters are super processed, present at just the right strengths for filming and help generate much more cinematic shots in broad daylight. Because we all know what happens when you film with an action cam with a shutter speed that is too short or when the camera even reaches its limits. Jerky and overexposed videos that look as if a cheap action cam was at work. And the GoPro can also be completely different, believe me! We use the GoPros on our FPV drones, i.e. the drones that you fly with such funny glasses. Here it happens extremely often that the exposure situation changes. And it's not a bad thing in itself if the camera regulates the whole thing automatically. But in order not to reach the limits of the camera in bright light, ND filters are also really useful here. And here we not only have ND filters, but even a combination of ND and PL filters. So the reflections can also say goodbye directly. Also especially cool when flying over water. In summary, the K&F Concept ND/PL filters are a great addition to camera and drone enthusiast's gear. The filters are of high quality and ensure more cinematic shots, especially in bright daylight. Glare and reflections can also be reduced thanks to the combination of ND and PL filters, which is particularly useful when flying or filming over water. Overall, the K&F Concept ND/PL filters are a worthwhile investment for anyone looking to take their recordings to the next level.

Filters for Gopro Hero9 really good and quality. Very nice also aesthetically with a metal frame that perfectly matches the Hero9's lens. Because these filters mount, replace the original Gopro lens cap and don't put them on it. They are easy to use and apply, packaging is minimal with a very handy transparent plastic case containing filters and a cloth for cleaning. Really a good product

Excellent quality and works great with GoPro 10 Black.

I use the filter on a Tokina 12-24mm wide angle and on a Canon 18-135mm here with a step up ring. The polarizing filter does what it should but with the ND filter there is a "darkening" from 50% to the middle of the picture. A strong black shadow becomes visible. This notorious "X" shadow in the image is manageable with variable filters in this price category... I have individual ND screw filters for the lenses mentioned above up to ND 1000, so I don't have these problems. The filter comes in a padded case Transport box made of plastic, this is perfect for safe transport.
