Quote from the review at GideonTech:
“The control buttons for the player are very simple. One oddity about the setup is that the middle toggle switch labeled Select, doesn’t actually do anything when pressed down. When you want to view menus and such on the screen, you have to press to the right to view it. A bit strange, but you get used to it.
The toggle on the right functions as the play, pause, stop, forward, back buttons. It also acts as the Like and Dislike buttons, which lets you choose which songs you wish to add to your Like or Dislike list. On our model, these buttons didn’t seem to really work like they should. During playback, it would only work sometimes, it felt like the buttons weren’t registering our choices.”
