High-definition optical tracking
You’ll enjoy responsive and smooth cursor control with the high-definition optical tracking (1000 dpi).

Durable keys
The keys can last up to 10 million keystrokes** so you can keep typing long after many keyboards have called it quits.

Easy-to-read keys
The bold, bright white characters make the keys easier to read—perfect for those with less-than-perfect vision. They’re less likely to wear off, too.

Logitech reliability
You get the high quality and reliability that’s made Logitech the global leader for keyboards and mice at a price you can afford—plus a 3-year warranty.
