Typing this comment from the Pro L with Cherry Brown. I really enjoy this keyboard.
I first bought the Corsair K70 RBG but was very disappointed by the quality and RGB settings not working under Linux (also it had more advanced useless RGB settings). I then bought the Pro L and returned the Corsair since the Pro L was superior in many ways.
Upsides: Simplicity, quality, software AND key controlled RGB colours, 4 easily accessible profiles, standard keys.
Downside: No direct media keys (need to use FN + key), keycaps are not PBT.
Hope this helps.
