No complaints on the Action 5. These aren't too hard to press on to the lens and hold strong enough to not get knocked off. The cleaning cloth is appreciated since fingerprints seem to be a required part of the installation process. Other than the polarizing and darkening I didn't notice any impacts to image quality but I'm not pixel peeping when using an action cam. These fit even with the case on the camera.

This set of six "push on" filters fits over the lens of my DJI Action Pro 5 snugly. It takes some effort to push them on (and pull off). They won't accidentally come off. They come packaged in a flat (0.75" thick), but relatively large (6.25"x6.25") plastic & fitted foam case. This case is too large to fit inside any of my "action cam hard cases" as is, but you could re-package the lenses if you found a suitable "accordion fold" style holder.My DJI action 5 pro does a relatively good job changing the shutter speed to accommodate a wide variety of lighting conditions, and because of this the videos with the various ND filters look somewhat similar to each other. (Longer shutter times as you get up to the higher ND numbers may introduce motion blur where you wouldn't normally have it.)There is a visible difference between the normal lens without a filter, and with the polarizing filter attached. But just having played with them casually, I haven't found a use case where the filters are actually necessary for my Action 5pro to delivery good videos. So if you like to have options, or have a specific need for a ND or PL filter, they are nice to have on hand, but if you are trying to decide if you need them.....you probably don't.

Great filters but my only gripe is the case. It would be much nicer to have them stacked in a log shaped case as opposed to a large flat case that’s just big and awkward in my camera bag… otherwise no complaints.

The product does what it's supposed to do. It makes the image look much more vivid and better. Thanks to the simple installation, the lens is installed in just a few moments, which I personally really like. It also holds very strong so it can't fall off

K&f has good accessories for photography and this filter works very well on my Osmo action 4, although it gives a little violet tint to the image but is corrected during editing. For its price it works well

I purchased the PL and three ND filter set to use the PL to protect the lens from rain, grit, handling abrasion and bug splats when riding my motorcycle. The fit is good and installation is simple - just press it over the lens. I wish K&F sold a four pack of the PL filters as lens protectors because these are consumable items. The "nano coating" wears off easily. These press-on filters also make your action camera less of an action camera. The nano coating on the PL lens seems hydrophobic. Water beads and runs off fairly easily. However, the ribbed rubber press fit over the lens allows rain or humidity to enter the area between the lens and the filter where it fogs the lens. This situation typically resolves itself in a few hours after the rain if you don't want to disassemble optics and clean them when on your action camera adventure.

Be warned that these filters don't freely rotate. It's not a problem with the NDs, but limits the usability of the circular polarizer. Quality is top and work as expected.
