It is very easy to use, I like how it removes unwanted backgrounds from my photos without me having to do anything else! Nothing really; maybe that sometimes when you remove too much of an area its hard for your eyes but thats because there are no settings so if something happens just try again with different options until u get what works best :) Great product!! This can be used by anyone who wants some quick help removing their photo editing problems such as taking out certain things they don't want showing up and also adding new features onto themselfs pictures.
