Report I need Guide Challenger Prime Keyboard in Gaming Keyboards Posted October 31, 2015 This is an overview, not a manual or tutorial. I hope ThermalTake can show to customers detailed instructions for managing the devices they sell. Not spoken (in english) in a YouTube video. Some of us need a written manual for study and eventually translate to our languages. I paid my keyboard as any other did, and i think i deserve some serious customer attention.
