What gadget is this?

On asking, I found that 9/10 people took this for a mouse, but that doesn’t mean majority is always right. Now knowing that it’s definitely not a mouse, try it for another gadget?

You can control the volume and tuner by rolling the radio forward/backward and sideways respectively (forward and backward to control the volume, while sideways for tuning).
