I have this antenna as well as others and it performs as advertised. It is easy to use, just plug the usb connector into your computer, install the driver that comes with it and you are ready to go. It is small and works well with laptops, it is highly directional which lets you pin point a wifi signal to get the maximum signal strength. My laptop has a built in antenna and it works good, but there have been times where the Hawking antenna found signals that my built in antenna could not detect. This is not only a WiFi antenna, it also detects signals without having to connect it to a computer. After you have detected a signal then you connect it to a computer to use the antenna. It will even tell you if the detected signal is secured or unsecured.
