@coffcoff I returned the mechanical part of the vest system back to Hill Rom (they paid for the return with a prepaid box to send it in) and they were suppose to reimburse Medicare and my Supplement Insurance for the months I did not use it. I was able to do that because it was within a time period, window of time, where I could. I gave the vest and hoses to a friend who has a child with CF and volunteers in the CF Department at the Children's Hospital in town.
Just a thought if this might help.
