To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
The build quality is excellent and it looks stylish a rack. I had a specific use for the switch which was to run my IoT devices, WiFi Speakers, Smart Lights, Smart TV's on their network seperate from my computer LAN. The supporting application make it easy to configure, with basic knowledge of VLAN's and networking required. (For the Newbies if you want to do VLAN's you need a router capable of doing VLAN tagging). The POE ports with 250 Watts of power supply my cloud key and UniFi WiFi access point effortlessly. Plenty of capacity for powering POE cameras if so desired. I wouldn't recommend this switch if you only need dumb switching.
A lot of people have difficulty setting up Ubiquiti hardware but if you have a reliable controller Ubiquiti is easy to setup. I have over 100 of these guys all over the place. We use it to power VoIP phones and it pumps the wattage consistently and has not failed.
