After a brief e-mail traffic with the seller I get the money now inc. Shipping costs and must now keep even the cable, because it would only cause costs to send it back. After consultation with the IT department to me the lady has informed that I still prefer to resort to a Cat7 cable. All my Cat5 cable in the house (between 1 and 5 meters) but also work with PoE ...
That is so full 5 stars for the seller but unfortunately only 3 stars for the product.
But please do not be deterred from buying. The cable works great, but just not a PoE!
