Interested in ND filters to get you started

For a relatively low price you get a lot with this ND filter. The biggest advantage is of course the variability because, saving you an expensive and possibly complicated set of different filters. The filter comes in a film which is in turn in a bag, along with a rather cheap-looking microfiber cloth.
As described here several times, significant artifacts are also on my filter in the higher levels visible on the low but not.
At first it seemed to be a disadvantage that I can not read on the scale the exact value, but right at the first Try it became clear that the number is ultimately completely irrelevant, as long as the result is right. and roughly one can also be guided by the marking and adjust if need be indicated.

I think that you can achieve great effects as a beginner with this filter straight without having to expend vast resources for the same.
