Does what it says it does. Obviously with smaller Youtubers the coverage is not as good, but I imagine it will get better as the app grows. Highly recommended, it circumvents all the annoying in-video ads and other superfluous stuff.

This is great

One of the best add-ons I've ever installed. I can't imagine using YouTube without it! The extra settings in the options are a great addition too. Love how easy it is to add segments and the counter for how much time you've saved others or saved yourself is a cool feature as well.

it's really great!

This add-on made me create an account just so I could leave a glowing review. Can't watch YouTube without it anymore, every time I watch a video on my phone I'm thinking of the time I've saved with this add-on installed. Love the leader boards that track how much time you've saved for others, too. It's a nice touch that really helps you realize how much time you've saved yourself and others on YouTube. Can't recommend this one enough.

Most under rated add on there is

SponsorBlock works right out of the box (so to speak) and you got additional options for tweaking :)
