The keyboard is very nice, and looks to original keyboards come with PC but with a little enlightenment and more! 3 colors only, we would have liked to see more red or in place of turquoise. Only gripe is that the button has for the initiation and the selection of light is also used to "scroll stop". Thus: We support to turn green, the scrolling stop switches on a 2nd time for the turquoise is support, stop scrolling stops, a 3rd time for the blue one support, stop scrolling starts, we support a 4th time to turn off the stop scrolling stops.
