The K810 Illuminated Bluetooth Keyboard from Logitech is a brushed aluminum Bluetooth wireless keyboard that makes a perfect match for a PC, tablet or smartphone. Once paired, you can use it from up to 30 feet away from your device. The keys are laser-etched and backlit, allowing you to type in low light or even in the dark. The level of illumination automatically adjusts according to the light conditions of your room, or you can manually adjust it if you choose. A motion sensor detects your hands as they approach the keyboard and turns the backlight on and off to help you save power when you're not typing.

A very handy feature of this keyboard is that you can easily switch between your devices. At the press of a button, you can go from typing an email on your Windows PC to taking notes on your iPad to replying to a text on your Android smartphone.

The keyboard is designed for Windows 8, and features specific keys to help you navigate the Windows 8 style user interface. The Windows 8 Start key offers an easy way to get back to your start screen, while the App Switching FN key lets you go between your open apps. The keyboard also works with Windows 7, iOS and Android operating systems.

The keyboard charges via USB and affords between 10 days and one year of power, depending on the intensity of illumination and time spent typing. An on/off switch on the right side panel helps to conserve power when you're not using the keyboard. A battery indicator light turns red when you need to power up, and green when the keyboard is charging.

Type comfortably thanks to the unique Logitech keycap design. The concave key surface complements the natural profile of your fingertips and helps you better locate each key for an improved typing experience. The key edges are softly rounded so your fingertips glide smoothly from key to key. The PerfectStroke key system distributes typing force evenly across the key surfaces making every keystroke silent, natural and fluid.
