This is a compact wireless keyboard. It connects to Bluetooth-enabled computers and tablets without a receiver. No driver installation is required; simply pair it and it's ready to use. You can pair up to 3 devices and switch between them with a single touch. It features input modes optimized for Windows, Android, Mac, and iOS. Recommended for those who don't have much workspace, such as those working from home, or for those who find cables cumbersome. Includes instruction manual. I purchased this new last year but have never used it.
