Inexpensive, and inexpensively made. All plastic, which is not necessarily a problem, but it does make it feel cheap. The real problem is that the ring around this polarising filter is a real pain to turn, especially if you don't want to touch the filter and leave a smudge. And you must turn a polariser in order to see the orientation that is best for a given film/photo situation. A marker that indicates the orientation of the filter is lacking, so you have to check it every time. I haven't used it on the drone yet, so can't comment on how it affects the photo/film. Better to look for something of higher quality.
