I use this on my work laptop (microsoft surface pro) which I am using at home. This adapter means I can connect to the internet via ethernet cable without using the standard USB port, which is a real advantage, as I can now use the standard USB port for my headset. There are only 2 USB ports of any kind on this laptop, so it's quite limiting, but this adapter has sorted it for me. By using a wired connection to the internet it's faster, more secure, and means I don't have to turn on the wi-fi.
