CAdidn't boost the volume at all.. didn't boost the volume at all literally no difference between before download and after at 500% basically it's a slider that moves left to right and nothing else
Not satisfied

GBNot a very useful experience... Although the extension works, it does not provide the "500% Volume Boost" as boasted. Furthermore, the volume adjustment must be set for each and every single video every single time. Instead of setting it one time and forgetting it, the sound level boost must be set for each and every separate and individual video. Also, it's exclusive to youtube videos only and does not work on other video formats or platforms. Not very useful or really all that helpful. It would be better if the browser extension worked across the web browser platform, instead of on each and every single separate video on youtube.
