Unnecessarily complicated. There are better down loaders. Tried to down load a video before being removed from YT, this add on down loaded the wrong video on the wrong channel. I'd give it 0 stars if I could. Utterly useless.
Well......it when you can't download a video, it gives you the option to "buy" the "ultimate" version. Why not just do that? Offer the "ultimate" version from the beginning and bill before the first download.
