The keyboard is clean, used for almost a month, and I rarely play on it. Its response is fast, and its lighting is strong; you can dim and strengthen it. + There are many modes you can control for the lighting level and the speed of the lighting. It has a red switch, and the keyboard is clean, and it comes with an extra switch + the piece to remove the keys + the box. I hope not to undervalue it, and the price is 100 riyals.
