Does the job in the emergency

I opted for this product, but because I have a printer with fax only one LAN line. This line I can not expand and put no more so. Fax is not wireless, so you had to cheat a little. My reasoning was as
1. Divide the 8-wire cable to the patch panel
2. Adapter of RJ11 to RJ45 to connect my Fritzbox for FAX (4 wires away)
3. The rest of 100Mbit so more 4 wires away.
The printer arrived I conclude this part with a connector to the end of the line. From here, I can go with patch cable to the LAN port on the printer and with additional adapter from RJ11 to RJ45 to the fax.

Now came the shock. When I kept the part in your hands, I saw on the label incorrect wiring. Now it is not worthwhile to send the back and forth, so unpack and open housing. Loosen the screw and carefully pull apart and help out with the screwdriver. Then came the disillusionment. Connected (as I found later) as shown on the product photo and description. The description is quite at the bottom, between advertising under swapped.
And now now for Splitter.
The part is made of plastic and covered with some aluminum foil. I hope it appeals to the CAT5e requirements and I can transfer the data without interference. Frankly, I have for the price no longer even erwahrtet and yet disappointed. Would something like that be to have a shielded housing, I would buy at the higher price. If everyone wants to have cheap and cheaper, then have no other manufacturer than to build only cheap. Since we are to blame.
Thanks anyway for a free supply of lets-sell.
