AI-generated summary
For £58.32 ex-VAT, this is a sensible little “fix-it” PoE+ midspan if you’ve got existing gigabit data cabling and just need to power one or two devices without reworking the whole network. The big practical win is simplicity: it’s unmanaged, so you drop it inline, power it, and your APs/VoIP phones/cameras that expect 802.3af/at PoE get what they need. Wall-mountable also helps in real-world plant rooms/cabinet gaps where a desktop brick is a nuisance.
That said, I wouldn’t buy it if you’re planning for growth or you need real network management. It’s not a switch, it won’t tell you which port is drawing what, and with only two outputs you’ll likely outgrow it quickly in a busy site. Also, check your powered device’s requirements carefully—PoE+ is great, but not every device behaves the same way under load, so you don’t want a “30W on paper” mismatch. Overall: good value for a small number of PoE endpoints on gigabit links; not the right choice for multi-device deployments or anything where diagnostics and scaling matter.
