Enough performance is coming out with low power consumption.
Packing was simple but there was no damage.

Fast post was made. Was a product that I followed for a long time. I have owned it with reasonable price with SuperDeal. The product box is beautiful. Box content is complete and came with EU adapter as I marked on the order. The case of the product is metal and the ports are solid, rigid. I like it very much. Smooth 2.5Gbit and 1Gbit connection was achieved. I hope I can also try the 10G SFP module in the future. I ordered 5 ports in one. It also came up with the big case version.

Arrived extremely quickly to Japan. I don't have another SFP+ device to test with, but 2.5Gbps ethernet cables connect devices at the correct speed. Runs cool to the touch. Instruction booklet is a generic one for 1Gbps switches rather than one relevant to the product received.

It works fine, gives stable 250 Mb/sec, my HDDs are slower.

Excellent!!
