After using it for close to a month, I found this to be a budget friendly but very good quality black mist with variable neutral density filter for the DJI pocket 3.
The construction is quite good but not premium. The filter itself is made of glass with multiple coatings. In a month of intermittent "not so carful" use, there was no scratch. The glass filter has a little play in the housing and not quite as snug as I expect. Rotation of the glass filter is also loose without sufficient damping. The filter fits perfectly on the pocket 3 and the magnet holding the filter to the lens is quite strong.
Mist filters have become a popular tool among photographers. The mist effect on this filter is not very strong; there is a soft glow around bright objects, and softening of contrast and texture, which are the intended effects. The neutral density provides up to 5 stop reduction in exposure, useful in high contrast shots or very bright beach scenes. Haven't had the opportunity to try it on snow scenes yet! There is no polarizing filter.
There is no evidence of chromatic aberration.
The filter comes in a large protective case although most DJI pocket users tend to keep their filters in the neat filter slot in the hard case that came with the camera.
A screen protector is included in the package but I did not use it.
All in all, this is a decent black mist filter with a 5-stop neutral density filter that is well built. If you're looking for that black mist effect or need a neutral density filter for the DJI pocket 3 (this will not fit on a pocket 2!), it is a good choice.
