A pen has myriad usages depending on the person using it, circumstances and situations. Besides writing, it can serve as an object for playing pranks, expression of respect for intellectuals, playing games like pen fighter and what not.
The pen from Gadget4All also does one more thing in addition to all of above; it enables you to find a WiFi hotspot. The pen has been christened as Wi-Fi detecting pen. The four LEDs located on the pen shows the signal strength. More LEDs glowing means stronger signals. It is powered by two AG13 batteries, which look like small buttons.
The Wi-Fi detecting pen costs around $20.
