The Ethernet patch cable is very well made. It replaces cables that would not stay securely attached to my laptop computer. The only negative is they do not offer the cable in a length between 3' and 7'. This cable ends up in the same tangle as other cables that are connected to various pieces of equipment. Shorter would be better in this case. Other shorter cables are not shielded which is what I needed for this application.
My set-up is an AT&T Uverse self-install, and I found out after considerable trouble that one of the ISP-supplied ethernet cables was to blame for much of the noise being recorded on my gateway/modem. My problem was apparently "noisy" LED lights and computer and VOIP peripherals. A bit of additional research revealed that the default cables were not shielded, so replacing all the cables with something better was an obvious step.
These cables are well made and do their job at a better price than others I found. They're a bit stiffer than unshielded cables because of the extra layer, but that wasn't an issue for me. YMMV, depending on the source of any problems you may be having, but they made a worthwhile difference for me and I'm glad I bought them.
