Compatible with Logitech® Unifying receivers

Looking for a mouse or keyboard (or number pad) that is Unifying compatible? We’ll help you find the right one.

You don’t have to stay tied to your desk. Or live with the chaos of cords.

With Logitech wireless mice, you’re free. Free to be more productive and comfortable on the go. To keep your desk clutter-free. And to say “no thanks” to your notebook’s tricky touch pad.

With a variety of wireless options, you’re also free to pick which type of wireless works best for you. But don’t worry—we’re here to untangle all the terminology and technology.

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).

Even in the busiest wireless environments, such as a busy airport or high-tech office, Logitech Advanced 2.4 GHz wireless technology delivers the reliability of a cord plus cordless convenience and freedom.

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. It uses less battery power than other wireless technologies, too.

Just plain easy: Bluetooth®

No dongle, no cord—Bluetooth® mice give you a hassle-free connection to your Bluetooth-enabled computer.

Back to basics: 27 MHz

For a basic wireless connection, 27 MHz wireless technology is reliable. You can use it up to six feet away with less chance of interference in your home or small office because the band isn’t widely used.

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.”

In this article, we’ll power you through all the details and go behind the battery-life scene.

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.

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.
