* The perfect blend
- Traditional computer keyboards and laptop keyboards each have their benefits. Stand-alone keyboards generally use keys with longer, more comfortable key travel. Notebook keyboards have shorter key travel, but use a scissor-key mechanism that makes the response faster, compared to standard keyboards. We figured why not give you the best of both worlds? PerfectStroke creates the perfect blend of laptop and traditional keyboards by combining the smooth action of notebook keys and the comfort of traditional keyboards.

* Smooth moves
- You don’t strike the keys perfectly every time. Sometimes, you might just catch the edge of a key. With PerfectStoke, you won’t feel the difference. Precision micro-scissors distribute force evenly across key surfaces so every keystroke you make is natural and fluid - even the imperfect ones.

* Travel in comfort
- With a typical notebook keyboard, your fingers have to travel 2.2 mm to activate a key. Most desktop keyboards, on the other hand, have a much more comfortable key travel of 3.5 mm to 4 mm. We gave our PerfectStroke keyboards a 3.2 mm key travel - so you can enjoy silent, responsive typing that’s comfortable too.

* 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.

* Plug it in
- With the tiny wireless receiver, there’s no need to plug and unplug when you’re on the move. Or deal with the hassle of multiple receivers. The tiny Logitech® Unifying receiver stays in your notebook and lets you add devices as you need them.

* Forget about it
- The Unifying receiver is small and always ready. So small, in fact, you can leave it plugged into your USB port when you’re on the move—without worrying about breaking or losing it.

Add to it
It’s fast and easy to add a compatible wireless mouse, keyboard, or number pad to your receiver. You can mix, match, upgrade, or replace up to six devices—now or in the future—using just one USB port. To connect a new device, you simply open the connection software, click “Pair new device”, and turn the device off and on. That’s it.

* A tiny dynamo
- The Unifying receiver packs plenty of power. Built with Logitech® Advanced 2.4 GHz wireless connectivity, Logitech mice with the Unifying receiver give you the reliability of a cord—with the freedom of cordless. You’ll enjoy fast data transmission with virtually no delays or dropouts.

* 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.

* The power player: Advanced 2.4 GHz
- For the best-of-the-best wireless connection, Logitech® Advanced 2.4 GHz wireless gives you the reliability of a cord with cordless convenience and freedom. Advanced 2.4 GHz wireless virtually eliminates delays and dropouts—even in the busiest wireless environments, such as a high-tech office. In addition, Advanced 2.4 GHz wireless is designed to optimize battery power. (Many of our keyboards with Advanced 2.4 GHz wireless can offer up to three years of battery life.) Your keyboard is automatically paired with your computer. So, you can use your keyboard with the most demanding applications and know that every keystroke you make will be carried out instantaneously. It uses less battery power than other wireless technologies, too.

* Fast and reliable: 2.4 GHz
- The predecessor to Advanced 2.4 GHz wireless, our basic 2.4 GHz wireless keyboards deliver wireless convenience you can count on. Thanks to its ability to transmit data in two directions, your keyboard can save power by turning itself off when your PC is dormant. Your keyboard can even sense if there’s wireless interference and change channels to establish the most secure connection.

* Back to basics: 27 MHz RF
- An older favorite, you can use 27 MHz RF up to six feet away from your computer. It uses less battery power than devices that operate on higher-frequency bands. And it can keep a secret too—advanced encryption securely transmits your keyboard strokes to the computer.

* More power to you
- No one likes to run out of batteries. It’s a hassle. Scouring the house for new ones. Finding two that still have juice. Even making an extra trip to the store. At Logitech, we’re doing everything we can to make the hassle of replacing batteries hassle-free.

* Batteries
- Wireless keyboards let you avoid the inconvenience of cords. But unlike a corded keyboard (which is powered via USB and your computer), wireless keyboards use batteries, and batteries do run out of power. Don’t even want to think about changing batteries? We’ve got just what you need. You can choose a keyboard with a battery life of 15 months—or even three years—and practically eliminate the hassle and expense of changing batteries.

* Charge on
- If rechargeable is more your style, we’ve got those too. You just put your keyboard in its charging base. It’s that easy. (Plus it’s good for the planet.)
