Former point I can - for lack of comparative figures - neither confirm nor deny. For the price and the type of this filter, however, it should be clear that the quality certainly not with that of fixed filters worth 100, - Euro and can keep up. But that was not my expectation, with whom I have struck here.
I had - after reading a small gray filter tutorial (there was about 12 seconds exposed) - only ordered me a neutral density filter ND8, not knowing that there are different strengths. By I came with sorrow and distress at 1 sec exposure time -.> Packed and sent back.
Now that I lacked any experience I decided for this variable filter and regret not buying one second.
I hereby hinbekommen by day exposure times of up to 30 seconds and can play around and test their heart's content.
That was my wish, and that's what I got. And who exactly needs the same thing it will get here and will certainly not be disappointed :-)
