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.

See all mice with a gaming-grade laser.

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.

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.

A mouse makeover

Your mouse gets the job done. It clicks. It scrolls. It gets you where you want to go. It might even do some fancy things—like zoom or flip documents.

But did you know you can customize your Logitech mouse to work the way you want it to? SetPoint™ software makes it easy.

If you don’t have SetPoint, you can download it here.

If you have SetPoint, open it by clicking on the SetPoint icon (it’s the tiny mouse and keyboard in your tray, if you’re running Windows®) Or, you can select Logitech>Mouse and Keyboard>Mouse and Keyboard Settings from the Windows Start menu.

Your buttons, your way

Got a button you just don’t use? You can change its function to suit your needs. Maybe your mouse has a zoom button, but you’d prefer to use it for document flipping. Here’s all you need to do:

Pointer power

Your cursor is under your control with SetPoint. To move the way you want to, you can change the pointer speed and acceleration, turn on pointer trails, and enable Smart Move to automatically move the pointer to the default button in dialog boxes. In some cases, it also lets you adjust the scrolling speed.

Get ready for game time

Gamers, we’ve got a little something for you in there, too. You can enable game detection and choose game mode settings that give you the competitive edge.

Got juice?

Is the end near for your batteries? It’s easy to find out—you just click the Mouse Batteries tab to see how they’re doing. With some mice, it will even let you know how much time they’ve got left.

The power player: Advanced 2.4 GHz

Logitech Advanced 2.4 GHz wireless delivers even more robust, reliable performance than ever before, effectively eliminating delays and dropouts (compared to conventional 2.4 GHz and 27 MHz wireless technologies).

Your mouse is automatically paired with the receiver plugged into your computer and minimizes conflicts with other devices. So, you can use your mouse with the most demanding applications and know that every move you make will be carried out instantaneously.
