It works, you just gotta figure it out on your own.

You have to make the adjustments then hit that "eye" button to preview your changes. You cant see the adjustments as you make them. You got to click preview then exit & re-do adjustments, go back to preview, exit, make more adjustments, repeat till youre happy with your adjustments. You also have to figure out what the setting options will give you the adjustments you desire. Not very user friendly but it works & its free.
