I took this micro usb wifi-N to boost the connection of a notebook that had an integrated wireless card of 54Mbps throughput. This key has an associated 150Mbps router same power boosted my flow; I now surfs average: 120 to 150Mbps which is a plus for me. Easy to configure with the included CD, it also knows how to be discreet because of its small size and protrudes only very little of the USB port. There is also on this key, a dassociation button that allows you to connect to the router with one click. For now, very satisfied with my purchase.
