Peace, mercy, and blessings of God be upon you. I have a Corsair K70 MK2 keyboard. Size: 100% Switch: Red It has more than one button, including a button to raise the light, a button to lock the Windows button, a mute button for sound, and a knob to raise or lower the volume. It has a USB 2.0 port and connects with two USB ports. You can change the colors on the Corsair website. It comes with the wrist rest, but the clips are broken, and it comes with its box. Price: 300
