He delivers what he promises. I got about 930Mbps with it, which is what I get compared to regular 1000BASE-T. I'm a big fan of the metal case. However, the price is not the best. You can get it without the SFP transceiver and just buy your own transceiver on eBay. The cheap ones are fast enough and I found a 4 gigabit device for less than $2 including shipping. The TP-Link alternative is about the same, metal body and all, but cheaper if you add your own transceiver.
