Logitech® Wireless Keyboard K270. Reliable wireless-wherever you use your keyboard. The tiny Logitech Unifying receiver is small enough to stay in your laptop. Plus, you can easily add another compatible mouse or keyboard-without the hassle of multiple USB receivers. With Logitech Advanced 2.4 GHz wireless connectivity, you'll enjoy virtually no signal loss from up to 10 meters away.* You can go for two years without battery hassles.** Eight hot keys and plug-and-play setup that takes just seconds add to the simplicity. The familiar, full-size layout-including number pad-gives you all the right keys right where you'd expect them. And it's built to last with the high quality and reliability Logitech is known for-with a spill-resistant design*** and UV-coated keys for durability. * Wireless range may vary due to environmental and computing conditions. ** Keyboard battery life calculation based on an estimated two million keystrokes/year in an office environment. User experience may vary. *** Tested under limited conditions (maximum of 60 ml liquid spillage). Do not immerse keyboard in liquid.
