Used redragon keyboard. Red backlight only. I believe pressing FN + Home will change the illumination to a “breathing” type setting. Tested keyboard buttons on keyboardtester.comDoes not come with keycap/switch puller.Switches are clicky blues. The box states that the switches are customizable, but I believe the blue switches are soldered into the board and not removable. I was only able to remove the keycap.
