Its works way better than my old M510. Great sensor precision and I like that the center wheel in free mode. My only complaints are that the PowerCore to wirelessly charge the mouse isn't included so you can't wirelessly charge the mouse with your existing Qi chargers. You are forced to buy the PowerPlay mouse pad to get the PowerCore. Also Logitech G hub isn't compatible with older peripherals. I have a barely used G510 keyboard that cant be used with G hub so must have the legacy LGS (logitech gaming software) app installed in order to control my keyboard parameters and LED. You can't sync RGB LED between LGS and G hub, at least not natively. still looking for a 3rd party solution.
