Great. It can download a lot of files, and I use it to download easily other files than videos actually like SFW flies and such, it is really good at picking them up from the page, even when the file does not run, like typically flashplayer files. Very useful, although a bit niche I suppose, but it does work well with videos as well.

A must have if you want to download files in general, and above all a must have to download some files that you cannot download by other means like Youtuber downloaders or Atube catcher.

Alas, although it is one of the best at downloading files of all kinds, there are still some files it does not manage to find and download on some pages. But it might be the same for all similar softwares, add-ons and services... I hope these softwares will continue to progress in that direction so we may never again find files we cannot download on the internet.
