The set includes 6 filters: CPL to reduce reflections and improve colors, four neutral density filters (ND8, ND16, ND32 and ND64) to control exposure in different light conditions, and a Black Diffusion 1/4 that gives a smoother and more cinematic look to recordings. All are made of high-definition optical glass and have a multi-layer nano coating that, according to the manufacturer, reduces flare and improves color accuracy. The finish is metallic and quality is evident in the construction.

The mounting system is threaded, you have to remove the protective glass from the camera and screw the filter directly in. This is slower than clip filters but also much safer for use on the go. I have tried pressure filters in the past that have been released when recording in situations with vibration, they are very well held and do not move. The filters enter the thread smoothly without resistance or looseness.

In real use, ND filters work very well to control exposure on sunny days and achieve slower shutter speeds without overexposing the image. CPL effectively reduces reflections on water and shiny surfaces and improves color saturation without leaving it artificial. The image quality remains sharp without loss of detail or vignetting in the corners. The coating repels water droplets and fingerprints well.

The only thing that requires a little practice is to adjust the polarization angle according to the orientation of the camera relative to the sun, but this is normal with any polarizing filter.
