Can the mouse be used with a Logitech Unifying Receiver?
Can the mouse be used with a Logitech Unifying Receiver? Or is Bluetooth the only way to connect the mouse aside from the USB cable? Also, can the battery be replaced?
Yes, the MX Master uses a unifying receiver. In fact it can use up to three unifying receivers, with a button on the bottom you can use to select which of the three PCs the mouse will be paired with. Since my keyboard already uses a unifying receiver I put the unifying receiver that came with the mouse in my laptop and now I can use the MX Master with either my desktop or my laptop at the press of a button. :-)
As for the battery, I fear it is non-replaceable. You would have to peel off the slick pads on the bottom of the mouse to open the case, I doubt they would go back on quite right when you are done changing the battery. :-(
