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.

Uniting your setup

Your laptop is convenient. You use it on the couch, in the kitchen, at the coffee shop—wherever you want. Logitech makes your laptop as comfortable as it is convenient with portable mice and notebook-ready keyboards. The Logitech® Unifying receiver takes convenience a step further. The Logitech® Unifying receiver is a tiny, leave-in wireless receiver. Smaller than most coins, the Unifying receiver not only makes it easy to use a wireless keyboard, mouse, or number pad, it also works with up to six devices.

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. 

And, oh yeah, it’s got precision handling too. With normal click-to-click scrolling, you can navigate your lists, slides, and images with the line-by-line control you need. 

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:

• Open SetPoint
• Find your mouse
• Choose the button you want to change
• Pick what you want it to do

With some mice, like the MX™ Revolution and VX™ Revolution, you can even assign different functions to a button for different programs.

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