This device is great for road warriors as well as those who travel often. Ever wondered whether a certain establishment has a WiFi hotspot? Wonder no more with the WiFi detector pen from Informatica. For just $18.95, you get a device that is able to detect whether you're in a WiFi zone or not, as well as displaying the signal strength via the color of the LED. A green LED denotes that you've hit the motherlode, while a yellow LED shows that the connection is average, and a red LED means you probably might suffer from dropped connections while surfing the Web. Of course, the range of detection is pretty limited at a maximum of 50 feet, but what do you really expect at that price? Lest not we forget this is primarily a pen, you can use it to sign your multi-million business contracts by twisting it open. A third functionality within the pen is a white LED at the very top of the pen that could be used as a mini-flashlight.
Pros : A cheap solution to find WiFi hotspots
Cons : Limited range
