Review on CAT6 Plenum Cable 1000Ft (CMP) Computer Accessories & Peripherals and Cables & Interconnects by James Dominick

I'm a professional and I've run more wires than you or I can count. I have quality tools and am good at my job. This cable sucks. I tried several different ports and they all failed the connectivity and speed tests. After working through about 20 rows, I started trimming the ends. Just to keep trying to fix the "problem". After replacing the wire with a well-known quality brand. old, the problem is gone. I spent another $40 on connectors and products to diagnose the problem with this cable. In the end, it's not worth the risk. Buy REAL copper wire. Not that brittle copper-coated aluminum.
