I use this happy little add-on every day. I like that it gives me the option of choosing the quality of the video (saves me a LOT of data usage), and it is quick, easy, and simple.

It does not download the ads that accompany YouTube videos, even if I do watch them or allow them to play. It only downloads the actual video (more data savings).

It does not get crossways with my security software. It will rarely do something odd, like give me two download buttons that do not work at all, instead of just one download button that DOES work...but all I do is start the process over and it comes up just like it should.

I have never had it download anything other than the YouTube video that I asked for: no ads, no viruses, no malware, no porn.

I have no complaints. This is a most valuable piece of work!
