It actually does work! And pretty fast. As you click download button on top (assuming you downloading video) it drops you to other page where video link is already prepaired and video already snatched. Its not as snappy but its fastest method on what you can get. At least you do not need to wait for anything on that second page, so its good!.
As for downloading pictures... It does the job, but its not as fast as other tools like: "Image MAX URL" witch is universal tool for many websites.
