After reading the description and jacket of these Cable Matters Cat6a Ethernet Cables, the manufacturer will convince you that they are very high quality Cat 6a cables with two types of best shielding ( STP/FTP) . ). You are not! These are very thin, thin wires with poor shielding and not many twists and are indistinguishable from Category 5 cables. If you are reading this I would like a refund, false advertising.
