Excellent value -- though I was really looking for the 4+2 unit, which is even smaller and more efficient -- unavailable from AliExpress for now. The power supply is 18W -- 12VDC/1.5A.

Perplexingly the instructions refer to a web interface -- I assume for the managed switches in the range.

Great device to upgrade my network from 1Gbps to 2.5Gbps. I don't have a use for the 10G port yet, but I'm consistently getting 300MB/s (2.4Gbps+) when transferring files. And the price is just right, just a few dollars more than a 1Gbps switch

The Switch arrived in an immaculate state (new), looks and feels robust. It works wonders, I was able to perceive the improvement in my data network and also when browsing the internet. 100% seller recommended. It only took 11 days for my purchase to arrive.
