The good news is that I have an old machine that still works.
The bad news is that it gotten through another DME that I don't do business with anymore. When I got it, they didn't bother to tell me they were out of network. Of all my DME's I've used, I like the current one the best. Locally owned, by the son of a retired coworker (teacher).
They have given me super service. Though I don't look forward to dealing with it.
