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 33 ft away. 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.
