I have had this filter for about 5 months and i love it. I prefer the screw on filter to the filter inserts, personally. I mainly use it to create motion during day time photos. Either clouds or water from the ocean. I feel that for the price is this a great option and a great competitor to some of the other brands that 4 times the price.

Beware of use with step rings. It is extremely difficult to remove if over tighten on to a step ring.
