NETGEAR GS308E

6.2/10verdict: good, not the best

The NETGEAR GS308E is for people who want a small, silent eight-port Gigabit switch with basic VLAN support. It suits homes, bedrooms and desks where a fan would be a nuisance and plug-and-play setup matters. It is a poor fit for anyone who needs PoE, faster than Gigabit ports or deep Layer 3 management.
