Looking for a pair of Bluetooth (not proprietary) keyboard and mouse to use with windows devices as well as android ones. I'm fine with purchasing them separately as well. Don't want to spend more than 1k, cheaper the better.
No its not. It, like most wireless peripherals, uses a custom 2.4 ghz signal and requires the usb reciever that comes with it to be attached to host system at all times. Bluetooth devices don't come with a reciever since they can connect to a pc/smartphone's inbuilt BT controller.
