Power over Ethernet port is a real plus because it simplifies wiring or switch if your router is compatible.
Installation is a bit complex for beginners because of different network security options and the fact that the instructions and interface are in English does not simplify things.
Anyway, its size therefore intends it for professional use (it is like a beautiful big soup plate).
If you are an individual looking for a relay to extend the range of your wireless network rather look WIFI repeaters side. The Netgear WN3000RP v2, for example, less than 40 euros, a very good reputation.
