I recently purchased a G308 switch to replace a 10 year old G308 that was crippled - not destroyed - in a lightning strike. That G308 worked flawlessly for a decade without ever being touched. The fact that G308s enjoy such a long term production says something about its reliability and the reason I chose to purchase a second as a replacement for my crippled unit.
This device was extremely easy to set up. Simply plug the power in and connect the ethernet cables. No logging into a system required. It transfers the desired speeds to all of my devices.
Straight out the box no complicated wires, register your device in minutes then you are off and managing all your internet connections. I highly recommend it!
