Moreover, difficult, indeed, to get a real idea on the photo but it is really small (it held in the palm of your hand)!
Another excellent point is that it can be powered from the USB / Jack AC cord and therefore not need to use an additional wall outlet (transformer / power cord supplied also) to make it work. This, of course, provided that you have an available USB jack on your device to be connected.
It also comes with a small RJ45 network cable category 5E.
Small weak point for some, perhaps ... No support WiFi 5GHz only the 2.4Ghz with up to 300Mb / s.
But as stated above, it is already powerful enough to broadcast (or rather receive in my case) HD streaming videos!
