The power of convenience

For you, having a wireless mouse is all about convenience. Any time you need new batteries it’s a hassle.

That’s why we’re hard at work figuring out ways to extend the battery life of every mouse we sell. And it’s why we make some mice that let you go more than a year without changing the batteries. Because we happen to think that fewer batteries are better for you. (And better for the planet, too.)

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.

Pick a mouse with batteries that last a year, 15 months, 18 months—or even three years—and you might just forget it runs on batteries at all.

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.

Check out all of our rechargeable mice.

Bells and whistles

Mice that turn off automatically. Buttons that help you conserve battery life. Battery indicator-lights.

Many Logitech wireless mice are designed to help your batteries last longer. By automatically putting your mouse to sleep when you aren’t using it. By offering On/Off buttons that let you manually turn off your mouse. With battery indicator-lights that help prevent surprises—so you know you can count on your mouse when you need it most.

Some mice combine auto off, On/Off buttons, and battery indicator-lights.

One spin is all it takes

Scroll. Lift finger. Repeat. And repeat. And repeat.

Sound familiar? If you’re tired of inch-worming through long documents and Web pages, take hyper-fast scrolling for a spin to fly instead of crawl.

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.

That’s where hyper-fast scrolling comes in.

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.

Details, details

There are two kinds of sensors: optical and laser.

Mice with optical sensors track the surfaces beneath them using the available light and an LED lamp.

In 2004, Logitech introduced the first mouse with laser tracking. Laser sensors, compared to optical, produce far more illumination—both of the surface and of the contrast created by, literally, specs of dust on the surface—revealing a wealth of details even on glossy surfaces like highly polished wood. And that means your mouse can track motion precisely on many surfaces, without lags or jitter.

Gaming-grade control

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.

Track tested

We rigorously test all of our laser mice on a wide variety of surfaces to make sure your mouse is free of tracking flaws.

* Mice with Logitech® Darkfield Laser Technology cannot track on glass that is 4 mm thick or less, which is not much larger than the head of a pin.

It all adds up

Do you spend a lot of time with your mouse? Repeating the same hand and arm movements over and over again hundreds, if not thousands, of times a day? Even the littlest difference in design can make a big difference in your comfort.

Logitech mice have all sorts of features that help increase your comfort and help reduce the amount of movement, effort, and strain needed to get around your computer.

A natural fit

If your hand had a choice in the matter, it would naturally take the angle of a handshake when your arm is bent.

We figured nature might be on to something and created mice that are sculpted and sloped to let your hand take a more comfortable, handshake-like position. And that means your hand can relax.

See all sculpted mice.

A better grip

You lift and move your mouse again and again, all day long. If it’s hard to hold, it’s going to put a little extra strain on your hand. But don’t worry—we added non-slip rubber grips to many of our mice to increase friction and make it easier for you to hold and grab your mouse without squeezing.

Pick out an easy-to-pickup mouse with rubber grips.

All about angles

Extending your wrists and flexing your fingers for hours may not feel so good. That’s why we make low-profile mice that reduce the angle you need to extend your wrist. And we carefully place controls so that most hands can use them without flexing fingers more than 45 degrees.

Navigating to comfort

Comfort features aren’t the only ones that help your hand out. If you can get where you want to go faster, your hand does less work. Less work equals more comfort.

Hyper-fast scrolling lets you fly through 10,000 lines of a spreadsheet with a single spin of the nearly frictionless wheel—something that would take 1,000 spins and seven minutes to do with a traditional scroll wheel. In the long run, that’s a whole lot less work that your finger has to do.

Check out all mice with hyper-fast scrolling.

Want more time-saving controls that can save your hand, too? Side-to-side scrolling plus zoom, application switching, and Forward and Backward buttons all help you do more things with less effort.

See all mice with advanced navigation controls.

Smooth moves

Is your mouse fighting your moves? We’ve got mice with slick, low-resistance feet that allow them to glide more smoothly than your average mouse. When your mouse resists less, you don’t need to work as hard.

Find a mouse with low-resistance feet.

The easy track

You can even choose a mouse that doesn’t make you move very much at all. A trackball mouse stays in one place—you just move the ball with your finger or thumb. Plus, customizable buttons help you do more, more easily.

Check out all trackball mice.

If you love the convenience of long battery life, Logitech mice will make you happy. In fact, the Logitech® Marathon Mouse M705 will last you up to three years without a trip to the store for two AAs.

But do you ever wonder how we determine battery life? And what about the disclaimer that’s on every box? “Battery life may vary based on user and computing conditions.”
