Working good!

I had some problems downloading at first. So I deleted the add on, and reinstalled it the following day. Since then, it works brilliantly. I highly recommend this add on for downloading informative youtube clips.

It's really great and easy to use

I have tried quite a few addons to download YouTube videos and this is so far the only one that works.
