I bought these cables to replace various cables for connected devices in my house. Previously, I couldn't get anywhere near the internet speed I paid for on the device. I went through a few troubleshooting steps to discover that it was my cables limiting the speed between my Arris modem and Google Mesh WiFi, as well as other devices in my house that were interacting with my other Google mesh "washing machines". were hardwired. After the upgrade I get full speed (300Mbps). With my old cables I got <100Mbps.
