It does what is says it does, but I'm disappointed that it can't remember what volume I set a tab previously. Every time I am on Facebook or Insta I want the volume set to 10%, otherwise the stories and video volume blasts way too high. I wish I could set it to automatically set certain volumes for certain URLs. It's a bit annoying to have to set it every single time manually. But again... much better than not having it at all!
