First off, this is an awesome product, totally plug and play with absolutely no configuration required whatsoever. Simply plug in your cables and off you go - it automatically detects whichever port has the connection from the router and the which one is connected to your computer or other devices, you don't have to do anything.
I use mine to connect an AV receiver, Smart TV, Sky HD box and HTPC to my home network. I simply plug in the various devices to this switch and then run cable between it and my main router. Everything connected and configured automatically as soon as it was plugged in.
For a stress test I streamed HD content to the Sky box over the internet, over the Smart TV and over the HTPC. I also sent two Blu-Ray rips from my NAS to the HTPC, each one averaging roughly 25 mbps. All the streams worked perfectly and the switch only got very slightly warm to the touch.
A final good point - the power cable and the ethernet ports are on the SAME side of the device. Many switches have these on opposite sides with is a pain for cable management.
One ANNOYING point -
The older version of this switch would adjust the colour of the LED lights on the front to indicate the speed of the connection over that port. That is, if you had a 100mbps device it would turn orange whilst a 1000mbps device would turn the indicator green. This is quite handy for quickly checking the network is operating as fast as it should.
This particular switch seems to simply stay green, despite the speed of the connection. I've tested it with several confirmed 100mbps devices and a green light is all you get.
