MORE PORTS
Eight 2.5GbE ports in a fanless metal body with ~40 Gbps of switching capacity — nothing to configure, nothing to hear.
NO REWIRING
2.5GbE runs at full speed over existing Cat5e at typical home runs under ~45m — you do not re-pull a single cable.
UNDER $150
$80 typical — $70 of headroom in a class where near-identical 8-port 2.5GbE switches reach ~$150.
RUNS 24/7
Roughly 1W idle in ServeTheHome's testing — about as low as fanless 2.5GbE gets, versus ~5W on older designs.
PROVEN PICK
Amazon's #1 best seller in networking switches per ServeTheHome, with the per-port status LEDs cheaper BrosTrend units omit.

  The catch — co-equal billing, always

You are paying 4x for headroom you may not use. The gigabit TL-SG108 does the identical job for ~$20. The 2.5GbE premium only pays off if a NAS, Wi-Fi 7 AP, or gaming PC on your network actually has a 2.5G port — in a house where the heaviest task is 4K streaming at ~25 Mbps, it buys you nothing today.

Dealbreaker? Runner-up №1 is the same box at gigabit for $20 ↓

  Every product has a catch. Verdicts that hide it are how bad buys happen.

Runners-up — if your needs differ

Adjacent verdicts — same method

Traps — this verdict avoids

Trap 01

Wired ports, not Wi-Fi

A switch adds wired ports only — it does not extend or improve Wi-Fi coverage. If the goal is a better signal upstairs, you need an access point, mesh node, or extender. A switch will not add a single bar.

Trap 02

The brand premium

Near-identical 8-port 2.5GbE switches sell anywhere from ~$49 to ~$150 — you are paying for the warranty channel and idle draw (~1W vs ~5W), not for speed. Prices in this class are unusually volatile; check the live price the day you buy.

Trap 03

Unmanaged is unmanageable

Unmanaged switches have no VLANs, QoS, or link aggregation — perfect for a flat home network, wrong the moment you want to fence IoT cameras or a guest SSID onto their own segment. Get that wrong and you re-buy at ~$133.
