Backlit Keyboard
on December 2, 2025
Posted by: rpershell
Verified Purchase:Yes
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.
I would recommend this to a friend!

Excellent Backlit Keyboard
on February 14, 2024

Verified Purchase:Yes
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.
I would recommend this to a friend!

Good little Keyboard

These are good little keyboards. The backlight is between warm and white (not yellowish or blueish). I keep mine on the dimmest setting in a dimly-lit office/studio. An important point for me was having quiet keys and these are almost as quiet as any laptop.
