Good day. Does the Logitech mouse M310 have a Unifying receiver (not Bluetooth Nano) . I want to connect the to my current Unifying reciever from my Logitech keyboard K520 and not have to plug in a second different receiver on the laptop. If I order an M310 and this would not work, could I return the mouse? (I had bought a unit K520 keyboard and M310 mouse 3 years ago [which now mostly double clicks with the press of the left button] and I would like to replace the mouse equally [size]). Best thanks.
