Right from the time a pen was invented, it had multiple uses. Apart from writing it can be used to poke your friend sitting in front of you or rather dig your ears. But this pen from Gadget4All does all this and also one more thing. It finds you a Wi-Fi hotspot. It costs only $20 and the four LEDs placed on the pen display the signal strength. More the LEDs flashing, better the signal.
