Some benefits I find it to be really comfortable, however getting used to it takes some time. Smooth and very silent keys. Cool white lighted keys, useful Logi application! The battery lasts a very long time without the backlight. You can connect to both the built-in adapter and your own Bluetooth devices, particularly the 4.1 and 5 versions. Cons: I couldn't locate it on my own. But for some people, it might be a drawback because there isn't a button to activate the mouse's context menu (an analog to the right click), and that there isn't a Pause/Brake button.
