Easy to use (although a bit confusing if you're using it for the first time) and does as advertised.

The only issue I've seen recently is that videos on YouTube stop playing after a few seconds and an unexplained error prevents the video from playing every single time. Disabling this add-on instantly resolved this issue. I will change the rating to a 5-star as soon as I find a way for the addon to work again without this disturbance, or this issue is patched.
