I have never been happy with the internal speaker of my Acer Aspire Netbook...so I ordered this product and am very happy with it.  It is easy to connect and I very soon figured out how to charge it up.  I'm also using it to play my Apple Ipod music when I don't want to wear headphones or if I wish other people to be able to listen to my music.  I'm a senior citizen (78) so it took me a couple of years to realize that I could hook up an external speaker to my Netbook and now I'm very happy.
