What to know before buying

The listing describes desktop and wall mounting but does not state that mounting hardware is included. The listed maximum power of 240 Watts is unusual alongside the stated 5 Volts supply, so confirm the intended power specification before relying on it. Customer reports of 600-1000Mbps are individual experiences, not guaranteed throughput.

Customer feedback highlights easy out-of-the-box setup, compact size, stable operation and adequate Gigabit speeds. One reported speed range was 600-1000Mbps across devices, which is an individual experience rather than a performance guarantee. This feedback makes the switch sound suited to straightforward wired expansion, while the supplied listing specifies five unmanaged RJ45 ports and a 1000 Megabits Per Second rate. Aggregate ratings are broadly positive but do not establish why every customer rated it as they did.

Positive themes

Customers describe setup as easy and report that the switch works out of the box.
