The build quality of the cable affects quality, the plug contacts sit top in routers, switches and network cards. Parallel laying with power cables is not a problem with the cable shield. My data throughput has quadrupled to conventional CAT5 cables in GBit LAN (appropriate hardware provided). Now slow down, only the hard drives. Even my Internet connection has become a little faster when downloading. In use there are 2m lengths and 10 m lengths. For the offered price is a very good product. Strong buy recommendation
