Have a CPAP Machine? Beware of GAME OVER

You used to be able to buy used ones on Ebay of Facebook marketplace, but they seem to have blocked them from those formats. I actually am going for a sleep study in about 2 weeks to replace my ResMed S9 that I have had since 2014 that has about 31,000 hours on it. Mine has the same warning on it but still works ok.
