This is simple, streamlined, easy downloading for the reference videos I use. I have spotty internet so having access to a local copy of the video is important to me. Recently the service was interrupted by new YT coding. Random interruptions in service like this is expected and must be overcome. The developer of the add-on adjusted to the YT change and continued the service FASTER than any of the other options I have tried. Please note I have NEVER had a video downloaded from this service with unwanted additional content. And links to the service do NOT send you to infectious websites unlike a few other options I have seen. I paid for the PRO version a while back. WORTH IT. Definitely gotten my use from this service.
