Laser precision means you’ll enjoy smoother tracking on just about any surface.* Curious about cursor control?
Efficient power management
The low-battery indicator helps eliminates surprises. The smart sleep mode and On/Off switch extend battery life**.Big on battery life? We are, too.
* The laser sensor does not work on glass or mirrors. If you’re looking for a mouse that will track on glass, click here.
** Battery life may vary based on user and computing conditions.
One spin is all it takes
Scroll. Lift finger. Repeat. And repeat. And repeat.
Scroll a lot?
Your spreadsheets and documents are getting longer. Your digital photo and music libraries are bursting at the seams. And you’re glued to long Web pages that have you scrolling and scrolling and …. To get through it all, you’re doing a whole lot of scrolling. We’re talking 26 feet of it in your average eight-hour day, according to a Logitech study.
From zero to line 10,000 in 7 seconds
When you need to do some long-distance scrolling, hyper-fast scrolling unleashes the speed demon inside. What’s going on under the hood? The ratchet-scrolling mechanism you’re used to retracts so the wheel can spin with virtually no friction.
Powering your mouse
The power of convenience
For you, having a wireless mouse is all about convenience. Any time you need new batteries it’s a hassle.
On and on and on
The longer your battery life, the less hassle you face. No lugging around batteries when you’re on the go. No wasting time and money on frequent changes.
Charge, not change
Don’t want to deal with changing batteries at all? We’ve got rechargeable mice, too. You just place your mouse in its recharging stand or plug in the USB cord when you’re done using it, and you’ll always be ready to go.
Bells and whistles
Mice that turn off automatically. Buttons that help you conserve battery life. Battery indicator-lights.
Laser sensors: A controlling interest
Sensing the details
What does a mouse do? Fundamentally, it allows you to control your cursor. And the best measure of cursor control is the accuracy with which the mouse translates the movements you make with your hand.
Sensitive to your needs
Some people just need a mouse that works. Others need a mouse that can track on many surfaces. And gamers need a mouse that can give them game-changing precision at any hand speed.
There are two kinds of sensors: optical and laser.
Glass. The final frontier.
Logitech mice that are built with Logitech® Darkfield Laser Tracking™ use the smallest possible details to create a micro-road map of the surface. That means these mice can track on glass.*
If you’re an expert gamer, pixel-perfect tracking can mean the difference between victory and defeat. Our mice with gaming-grade laser sensors can track at speeds all the way up to 5700 dpi. So when the game is on the line, you’ll get maximum precision, blinding speed, and ultra-smooth tracking.
We rigorously test all of our laser mice on a wide variety of surfaces to make sure your mouse is free of tracking flaws.
Logitech® Darkfield Laser Tracking™
Now, your mouse works where others don't - even on glass.
You work and play all over the place—and that means you’re going to encounter all sorts of work surfaces. A glass desk or shiny table shouldn’t stand in your way.
That’s why we created Logitech® Darkfield Laser Tracking™, featured in the Logitech® Anywhere Mouse MX™ and the Logitech® Performance Mouse MX™.
Darkfield tracks on surfaces like clear glass* and lacquered desks that stump optical mice and standard laser mice. So now your mouse works wherever you do.
It’s all in the details.
Optical and traditional laser mice use irregularities in the surface to track the direction and speed of your mouse. The more irregularities on a surface, the easier it is for the sensor to track your movements.
But use your mouse on a smooth, glossy surface like clear glass, and there just aren’t enough imperfections for your standard mouse to work. This is where Darkfield Laser Tracking comes in. Darkfield uses the smallest possible details to create a micro-road map of the surface—so you get better precision on more surfaces.
Can this mouse do everything?
Just about. Keep in mind, however, that we haven’t designed the first two mice with Darkfield Laser Tracking for gamers or for those working on laboratory-grade clean glass.
If you’re making lighting-fast maneuvers and need gaming-grade cursor speed, take a look at the Logitech® G9x Laser Mouse.
And if you’re working on exceptionally clean glass, you may have to wait until the dust settles. For surfaces with fewer than 44 microscopic details (per square millimeter) that are less than 5 µm wide and 1.5 µm thick—to give some context, a strand of human hair is about 100 µm wide—you may want to swipe your hand across the surface before using your mouse.
But for everyone else, Darkfield Laser Tracking gives you precise cursor control on virtually any surface—even glass.
