I Love This Keyboard!
My large key backlit cheap keyboard started doing strange things so I ordered the HP 400 backlit wired keyboard via my HP Smart App. I got a sale price and delivery was quick! I love the smaller size of this keyboard compared to the big clunky one I had. This one is 14.75" wide, 5.5" deep (6" on the number pad end) so easier to type if you have small hands. The feel of the keys is soft and very easy to press. The light is white and has three brightness settings. There are two small "feet" in the back to change the angle if you want, or fold them down flat. I had to do a change to Windows Registry to make the NUM lock be on when I log on. You can find how to do that online, it's easy. I do have a very similar HP wireless keyboard but I don't like dealing with batteries all the time. This one works great with my HP desktop and monitor. No complaints!

Backlit Keyboard
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.

Keyboard could be larger. Keys could be larger. Light up keys are great.

Bright Idea in a Compact Package
At 78, being able to see my keys clearly makes a world of difference—and this HP 400 Backlit Wired Keyboard delivers. The adjustable backlighting with three brightness levels is a real standout. Yes, it does require a USB connection for power, but that's a small trade-off for such visibility. The keyboard is slightly narrower than a full-sized model with a number pad, so it took a little time to adjust to the key layout. Still, it’s a sleek, reliable option that’s easy on the eyes—literally and figuratively.

The backlighting is worth the added expense.
