Works perfect, simple, easy interface, can go up to 4x if you change setting.
Only one issue, I want an option for "Always ON", don't like that I have to manually enable on every video.

Works Well!

perfect, extremely loud <3

5 stars because it just works and looks nice

Extension describes itself as a button that boosts volume on youtube. It's a button that boosts volume on youtube. It looks like the other buttons and works like the other buttons. 10/10

Great extension, really handy for quiet YouTube videos. Using it is quite intuitive and fast.

I wish it works automatically. But it's good enough

Doesn't work. The 2X button is greyed out on the vids, and as a result, is unusable

works

Pra mim já é indispensável.

very useful
