Does what it says, quality of glass is very good, and screw mechanism is smooth, but maybe I expected a little too much from it. Change isn't too drastic, and honestly, can be easily replicated in Photoshop if you shoot raw(WHICH YOU ABSOLUTELY SHOULD). If you are looking for your first filter, go for ND filter instead, in my opinion.
