After my fifth Logitech G912 keyboard turned Satanic and started auto-typing on me, I hoped NOT to replace it with another Logitech and instead went with Corsair K100 RGB, I'm pretty happy except the RED LEDs are dim. But it has a good feel, somewhat lighter than the Logitech still a solid mechanical stop. The software that allowed me to set the key colors under Linux is ckb-next but it's sort of a pain in that it has to be running for the keyboard to retain it's colors, the Logitech I could set and forget.
