Great little switch

Poe worked flawlessly. Took five minutes to set up. Came with AC adapter but wasn’t needed as I have POE+ running along the home network.

Small Switch, Huge Performance Upgrade

The Ubiquiti Flex 2.5G 8-Port Managed Switch turned out to be one of the most impactful upgrades I’ve made to my home network. Setup was simple, and once integrated into my system, I immediately noticed smoother performance across wired devices. With 2.5G support, everything from gaming consoles to workstations now feels more responsive, especially during large downloads and data transfers. One of the biggest improvements has been network consistency. Devices that rely on stable connections — like streaming boxes, smart home hubs, and work equipment — now run without the slowdowns or interruptions I used to see. Despite its compact size, it delivers serious performance and works seamlessly within a modern multi-gig setup. It’s also great having managed features available without making things overly complicated. If you're building or upgrading a high-speed network, this switch is a simple way to unlock better performance across your wired devices. A small device that makes a noticeable difference.
