Perfect as it its. A volume slider & booster that works amazingly!

Genuine life-saver. Perfect for people like myself that have hard of hearing issues. Some videos are simply too quiet and this saves my life. Makes content way more enjoyable.

A great option for people like me who don't hear well to amp up the volume

As it says: simple and reliable. Awesome.

Nothing more, nothing less. Perfect.

Does what it says on the tin! Simple to use but an amazing improvement to browsing and youtube.

It works fine!

It's Good

Would be nice to be able to type the volume boost level desired, rather than move the slider or select level at increments of 100. Example, if 150% is desired, have to move the slider with the mouse back and forth to get the desired level.
