A:AnswerIt is probably because the packaging is intense. It comes with a little metal tin, the charging dock and some heavy duty foam. The mouse is not 5 pounds.
A:AnswerThe charging dock is also the wireless receiver so in order to use the mouse in wireless mode, it must be connected to a USB port. The mouse can also operate in wired-mode where the USB cable is unplugged from the dock and plugged directly into the mouse instead.
