This USB extension is 16cm long. Between male and female, there is a so-called. Gooseneck metal as we know it from our table or floor lamps. The diameter is here, however, only about 4 mm. So you put the plug in the PC and then can adjust the position of the socket so that, for example, a WLAN stick has better reception. The picture is misleading because although you can bend the gooseneck as shown, but it does not retain this position - he springs back !. Plug and socket retain a position of about 100 ° to each other. Provides you a more acute angle, it absorbs more or less back. For my taste, the gooseneck could be a bit stiffer, so the (considerably harder than a WLAN stick) could meet its set position with a TV USB stick.
