Technically, the cables are properly, the connection to 1 Gbit funzt easily and immediately. The plug connections are firm but not stiff. The only slight drawback is but due to the design and brevity and was taken by me consciously accepted: The cables are indeed flexible, yet very rigid. Tight corners can not be set. Long cables must be taken for this purpose.
Generally highly recommended, if necessary to buy what again if I have to expand my network.
