Seems to be working without issue, however I only give this addon 3 out of 5 as it seems to be limited to downloading a maximum of 720p, even if the video is 1080p or higher. Even the settings shows a maximum of 720p.
I also have "video download helper" installed, which allows any quality to be downloaded, depending on the video source itself, but this addon only allows up to 720p, and I have no idea why. There doesn't seem to be any "pro" version or a version which you can pay for to get access to higher qualities.
