    Two years ago I bought one of your Boostaroo amplifiers to hopefully cure a problem on my laptop. I couldn't hear the sound very well when playing a DVD during my travels via train. I bought your product to solve this problem and it worked! The sound is significantly louder when using the Boostaroo and it makes the movie-watching on my laptop very enjoyable. Thanks for the great products!

    This great little tool allows my wife and me to watch and listen to a DVD movie on my laptop computer on long plane trips with ease.

    I am one of the people who are sick of the volume problems with some of the recent MP3 Players. After plugging my headphones into the Boostaroo, the volume increased so much that it played all the songs at the perfect volume. This is great! Now I actually have control over my volume. Thanks Boostaroo!

    Your product has proved VERY successful in my line of work (military pilot). Because I wear ear plugs while flying.
