A question that was in any review, as the cable is because (apart from flat and "works", which even secondary school students recognize):
I tested two of these cables. Once 5 meters from the client to the switch and the switch to the file server again 15m.
The transfer speed is between 115 and 118MB / s when tested via FTP. More coming through a normal Gigabit cable either.
Conclusion
+ Low
+ To move well under carpet / door frames
+ CAT5e cables, no problems with GBit connections
-no screening
-to many people who buy such a cable to turn it on a daily basis and unplug and then wonder about defects)
