Box opened (to test the mouse) but the mouse was never installed/used.
Note: This is the "3" version of the MX Master not the newer "3S" version. Having used both versions, the main difference is that the 3S version has quieter clicks.
The mouse works with both Bluetooth and the Logitech Unifying receiver (the USB receiver is included).
These Logitech mice work great with Windows out of the box. They will also work with macOS and Linux but the setup is more complicated and requires some technical fiddling (not recommended for a novice user).
