There is not much to talk about with the physical design of the USB-N13. It is long, squarish and thin. It is also glossy black (which is nice). It looks pretty good to be honest.
This side has a few things that are worth noting. On the top there is a WPS button that allows you to setup a wireless connection very quickly. There is also a green activity LED right next to the opening for the leash.
The small size of the USB-N13 does not stop it from having some nice specifications.
