Summary: I had only one Ethernet port wall-jack near my TV, I bought this to connect my Smart TV, WDTV media player and the Satellite receiver. Its sites in the back of the tv stand and since its small hardly visible also the metal case design well blend with the rest of the systems.
Pros: Price got it on sale for $15. Nice metal Case. Working non stop since 2014 January. Just plug and play.
Cons: not managed switch, TP-LINK TL-SG105E managed switch would cost around $35 but does comes with VLAN etc
Summary: I hate networking. So I only connected this when I ran out of ports on my router. I didn't want to have to deal with trouble shooting network connections. I attached my D-link NAS device and the Synology NAS device I finally got around to configuring.
Pros: Was plug and play
Cons: None so far I will see how it performs long term
