This thing is loud! And very tiny! I was shocked at how loud it is! So far it is fantastic!! I am thinking of buying the GF one so she doesn't use mine!
What's great about it: portable ...LOUD for its size!
What's not so great: having to keep hitting the change song button to get to the songs you want to hear!
