I've tried so many video download add-ons and this is the one i've been the most consistently happy with. The devs for add-ons like these understandably have to play tag with YT all the time, but this developer is one of the faster & more dedicated ones from what I've seen. I'm big into media preservation, but it's a headache chasing add-ons that work so I'm really grateful this one has been so consistent. YT has once again changed how they work so the add-on isn't working at this exact moment, but unlike with a lot of others, I have faith that this add-on will be updated soon, the dev seems really dedicated. I rarely have any problems with this one.

Also I really appreciate how clear the list of formats & file sizes is when I use the pull down menu, and it's not cluttered up with too many no-audio or audio-only options.
