Keyboard as only briefly used for gaming. If you have never tried a Outemu red switch mechanical keyboard this is a good starter keyboard. It has RGB LED backlighting with black keys. It has some software you can download to do keyboard macros. This format keyboard is nice because it uses standard keyboard caps so you have the most options for replacement caps. Comes in the original box, barely used.
The mouse is a Redragon M612 Predator gaming mouse with the box only used a few times, they run $20 new.
I have a lot of mechanical keyboards and cheap USB hubs for sale. I can upgrade you to a Keychron C3 Pro with brown and red LED backlight for $15 more, or Keychron K8 with red switches and white LED backlight for $20 more. I have a one-handed Redragon keyboard for $15 and $8 for some Outemu black switches. Blue Gradient keyboard is $25.
