I won't go into the technical specifications since they're already extensively covered in the product description, but I'll share my experience and impressions.
I immediately tested this filter, taking advantage of the lighting conditions of the last few days. It's an "art"/"creative" filter, meaning it tends to create distinctive blurs and golden tones in shots.
The product is essentially a mist filter with the addition of gold particles that, when light passes through them, warm the image to a golden color, not the classic yellow-orange color.
The characteristic of the mist is to create a "fog" effect, which is accentuated in the highlights, where we have a sort of halo as if there were a light fog in front of the light source. At the same time, we have a slight loss of detail due to a sort of softness that is evident in the light colors until it almost completely fades in the contrasting or black areas. This is certainly not a problem or a defect, but rather its main characteristic, since it can be used to generate excellent highlights without having to go through post-production.

However, I found the use of the filter exceptional in the presence of LED lights shortly after sunset, as it creates a sort of very nostalgic image, where the LED lights take on the connotation of a softer light thanks to the halo that is generated, which is very reminiscent of the effect of neon lights. Furthermore, thanks to the golden cast provided by the filter, it pervades an overall warmth reminiscent of some very popular films of the '90s.

The filter is of excellent quality in terms of materials. With a Sony 18-105 I didn't notice any vignetting at minimum zoom, and the filter doesn't suffer from lens flare (as often happens with filters and artificial lighting).
If from a photographic point of view it's an excellent artistic filter, in video it's more than excellent. In videos it really manages to give the best of itself. It gives that retro touch that is clearly present in bright scenes and almost disappears in dark scenes, and we can play with this to create certain "vibes" during recording.

In conclusion, it's an excellent artistic filter, which, when used in the right scenario, gives us excellent effects. My rating is a full 5 stars.
