I am glad someone thought up this product. I hate having to boot my laptop to see if there is a WiFi connection in the area. This credit card size device is pretty simple press the button on the detector and you get a Green light if there is a Wifi Connection available. It’s only drawback is that there is no way to be assured if it is a open or secured connection. [www.idetect.com.sg]
The company is based in Singapore I am going to find out if they ship to the United States.
