Other reviews state noisy power adapters and such, nothing, it is fine, I also have the larger 16 port version of this, it also works fine, setup is easy, from the software tool it shows me no bad packets like another reviewer stated,, use cat 5E or better cable, I am using cat 6, QOS tagging, Vlan...
it is small; no noise; Vlan tagging is a must for me
no cons
