I have the MX Master 3, which was only superseded by the 3S recently with very little change.
1. Response time is imperceptible
2. It can connect directly via bluetooth, or with a small usb dongle. There is a button on the bottom of the mouse that lets you switch between 3 stored devices. It would be nice remap the device switch to a button on the top of the mouse, but this doesn't seem possible yet.
