Application:
Without installing anything I read the CD aside and put the Bluetooth stick into the USB port on the PC.
It was immediately recognized by Windows 7 (64-bit) and I had in the toolbar, a Bluetooth icon.
Right click on it and I was able to establish connection with my phone and send and receive data, quickly and easily.
Coverage:
In free environment outside perhaps really to 100 meters range. In our apartment, I would appreciate times as 15 to 20 meters, even through walls, mind you, it could receive from other rooms also good.
I can absolutely recommend. I got it because I like to load files from the PC to my phone and I did not feel like it times with a USB cable to connect each to the PC. With Bluetooth, it is now quick and easy.
