Yes, my wife took the M2 version when I upgraded to the M5. We find it pretty great, and it really is not much different from having a huge personal theater. The headsets appear to display the content in perfect sync. When sharing content with someone in the same room, it does not render a persona or avatar as it does when using FaceTime (where users appear as floating heads and hands).
Does she use hers for anything else? Do you ever use them with guests, or does the lens/glasses issue prevent that?
