Works brilliantly, exactly as advertised. I now have a moment of confusion whenever I see a sponsor segment, as it happens so rarely. On that point, uploading your own sponsor times to block them for future viewers is very easy, and can be customised to make the skip seamless. I'd recommend reading the guidelines before doing this though. I was hesitant about installing this initially as I was doubtful about how effective it could be, when all sponsorblocks had to be user generated and there are so many videos out there. However, I've rarely seen a video without the major sponsors blocked, and I'm very happy I installed this add on!
