The backlight does not illuminate the entire keyboard, some of the upper left keys do not reach the light. Feels very cheap but for the price of the combo that's no surprise. And there are only two possibilities for light, one is breathing and the other is motionless. There are no color options. The mouse is a bit heavier, not a nice lightweight gaming mouse. All in all, if you're on a budget, this is a cute and useful keyboard that will get the job done with little to no lighting options if you're ok with that. If you're looking for something more solid and cleaner for gameplay, I'd definitely say it's worth spending more money on better stuff. <3
