Works amazing and on SO MANY SITES. I love it.

Note: Many people seem to not understand why this app needs a local (Companion) app. Most streams send data in chunks, and now separate video and audio in the browser, and to merge those chunks and audio+video they need something on the computer to do that. This extension does this VERY well.

I haven't used it very long, but I also haven't seen any watermarks either. I will buy it, because I value it, but I can't speak to what others are saying about a watermark. I do wish there was more transparent info about that.
