Logitech Bluetooth® Mouse M555b

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.

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.

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.

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.

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 then 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.

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.

*At least 4 mm thick.
