We can’t say to a legal certainty that this is the world’s smaller 802.11n Wi-Fi USB adapter, and the way technology moves within six months it may no longer be the case anyway. But have you ever seen a Wi-Fi receiver this small?
One thing is for sure- it will have no trouble fitting in a Christmas stocking. What’s really nice about this item is it contains a Realtek chipset and works very well despite its small size. Because the case is small, it contains a small antenna, and thus your reception is not going to compare with some other long range wireless-N products we sell, but in comparison testing we found it worked about the same as basic range standard-sized USB wireless-N adapters from big brands (the 802.11g reception was not quite as good as internal cards on our laptops).
