How big is your mouse’s receiver? do you often forget to unplug it before putting your laptop into its bag? ah I know that feeling. I think we need a receiver that small enough to keep us out of the hassle with unplugging and plugging in the receiver, and thank to Logitech with its Nano-Receiver that make it possible. The receiver is nearly flush against the notebook – protruding just 8 mm from the edge of the computer.
