This backlit keyboard is exactly what I needed since my last backlit keyboard went wonky on me and have been using a non backlit till I found this one. No issues and the backlighting brightness is adjustable.
Perfect for my needs. Connects via USB-C cable and comes with an USB-A adapter as well. Backlight button to turn on, and can keep pressing to adjust brightness. Has no sensor, so stays on unless you turn it off, which is fine for me. Keyboard is very quiet as well. A professional keyboard with number pad, and not a gaming type keyboard.
