Despite the name, it does so much more than skipping sponsors. I actually find skipping intros, outros, and subscribe reminders more useful, because these are common than sponsors but just as annoying.

It's an absolute godsend.
Occasionally the servers don't work properly, but it's a fairly rare thing.

Gut

Been using this addon for about a year now and it's perfect. 27hrs of sponsors ads blocked. and I've contributed 33hrs saved. That's a lot of time saved for everyone.
