OK with limitations.
The filter does what it is supposed to do.Image quality: the filter effect works perfectly.Price-performance ratio: I think it's OK.Accuracy: the thread is well-made. (I can rate that because I work with threads.) Now comes another but. The filter is adjusted by turning the front ring, it happened to me that the filter could not be loosened again easily. I could identify two reasons for this. 1. The flat surface where the filter is screwed against the lens is a bit rough.2. Since the filter is adjusted by turning it, and the disk is turned with slight resistance (if it is OK, the filter is not adjusted by vibration either), the filter is screwed tighter and tighter against the lens. But otherwise the filter is OK
