Hello.. The mouse and keyboard have very, very fast response times since they are designed for gaming. The keyboard has red switches and customizable lighting that can change via software or directly through the keyboard buttons. The mouse has side buttons and a sensitivity adjustment button; each sensitivity level has its own color (you can control both sensitivity settings and colors through its software). The software is shown below in the pictures. The mouse pad is excellent with no issues—just needs cleaning—and comes with a cable for the RGB lighting along the edges. Reasonable offers are welcome, and I won't be short with the buyer 🙏
