Its a block of wood you set your phone on. Any phone really can be used for this. Literally any phone because it is a block of wood with a hole in the back that you put your plug through. In purchasing this I thought it was an alarm that you plugged you phone in and a speaker amplified your alarm. Nope, it is a block of wood in the shape of an alarm clock that you set your phone on. I'm going to start selling a Baseball glove Alarm Dock, just set your phone in the pocket of the glove and then thread your charger cord through. Boom essentially the same think as this, except it's better because you could use it as a baseball glove too.
Don't buy this product. It is stupid.
