This keyboard and mouse combo saved my day.

Style: 2024 Model

This keyboard and mouse combo saved my day. My same keyboard fizzled out and I happened to get this the next morning by 7am and went right to work with it. Just plugged and started. It feels exactly the same, easy to use. I'll use Logitech products for as long as I live . Their quality is phenominal.

Works Great!

Style: 2024 Model

This keyboard works wonderfully. The mouse works great. Couldn't be happier. My old keyboard had a broken spacebar, and the mouse scroller wouldn't work.

Nice tactile feel

Style: 2024 Model

Works right out of the box. Installation was simple. Probably should have gotten the next small size, as it is larger than I expected. But I like the key response and the feel of the mouse, so I'm keeping it. Nice, inexpensive keyboard and mouse.
