Not too rigid, not flexible - Perfect

Initially, the cables are somewhat stiff (which I as well as the current temperature outside sliding) after the cable 'thaw' two hours were they were somewhat too twisted for my taste. But this was also easy fix.
Both cables were laid without problems in the room and have similar no waves made, were nice and flat and straight after they have been once laid properly.

After I connected them I wanted to also test the same.
From my laptop and PC I then a download from my home server started.
The upload to my server then was stable 120 ~ 125MB and can then already be seen.

Possession of these cables now less than a month and can only repeat that my data throughput has 120-125MB Stable, my server is running 24/7 and must permanently provide data over the network / streaming.

Can only recommend this cable. Super quality at a great price!
