Depends. If you know that it's shutting down, are willing to handle the data exporting yourself, and also are willing to possibly pay rising costs for a Zeo unit and replacement headbands...
I know I don't intend to stop (already bought another 3 replacement headbands on Amazon), but I've already used my Zeo for a long time and seem to be pretty unusual in how much I use it.
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
