Review on High-Speed Monoprice Flexboot Cat6 Ethernet Patch Cable - Network Internet Cord - RJ45, Stranded, 550Mhz, UTP, Pure Bare Copper Wire, 24AWG, 5ft, Black by Jon Brazil

I bought (10) yellow Monoprice Flexboot Cat6 Ethernet Patch 550MHz Cables. The goal was to power my network components with these short 12" cables. Shortly after installation, I noticed that various parts of the network would not connect. When connected, a light touch on the cable will result in disconnection. Very loose to fit .I've built my own patch cords after this experience and no longer have dropout issues. Also, the cords are not rated for 550MHz. It is printed directly on the cord as 250MHz. These cords are being returned.
