Excellent. Does exactly what I need it to do. Low volume has been a problem with my laptop for a long time. This app solves the problem. Good job!

Solid. Increasing volume doesn't ruin the actual quality and haven't experienced a website that it doesn't work on. Wish it was verified to make me feel comfortable using it.
