Just 3 mm long, our smallest-ever wireless receiver practically disappears in your computer’s USB port. Since there’s no need to unplug it when you move around, it’s ideal for portable computers like laptops and Ultrabook™ devices.


Connect up to 6 Unifying-compatible devices to the same receiver. Add a keyboard, switch between mice, mix and match to fit your lifestyle. All without having to change receivers or sacrificing another USB port.

You get the reliability of a cord with wireless convenience and freedom—fast data transmission and virtually no delays or dropouts.

18-month battery life**

With up to 18 months of battery life from a single AA, you can almost forget about changing batteries. Smart sleep mode and an On/Off switch save power, while an indicator light eliminates surprises.

Logitech Advanced Optical Tracking

Laser-grade precision tracks over the most challenging surfaces—including smooth, glossy surfaces—that are problematic for standard optical mice. All while using less power, so you get longer battery life and more convenience.3
