The quality of the All Day Set is outstanding. The gases fit perfectly and are easy to assemble. In total you get 6 filters.

- ND4
- ND8
- ND16
- ND32
- ND64
- ND1000

These filters have the same function as sunglasses. If the light is too strong and your picture is completely overexposed, you can darken the picture by using the filters and thereby save your pictures. Due to the fixed aperture of the Mini Pro, this makes a lot of sense as soon as you want to photograph a snowy landscape or water in a bright sun.
However, I find the composition of the set a bit unfortunate. Because you will never need the ND1000. I filmed the sun directly with it and the picture was too dark.
I guess the set "CPL+ND8+ND16+8*Propeller" is the best choice overall. The set is much cheaper. The blackout with ND 8 and ND16 is completely sufficient and the additional CPL filter (polarization filter) is a great way to eliminate unwanted reflections.

Conclusion:

excellent filter quality and accuracy of fit. And an extremely sensible purchase for all drone owners.

PS: I weighed my drone with filter. The weight was 249.8 g and thus below the important 250 g mark.
