My only issue comes with the process of getting a new machine.   I have been a CPAP user for a few years already and my machine died. The process to get a new machine took 2 weeks which I feel is a bit long. For 2 weeks I had poor sleep quality, felt tired and crabby.    It's well documented how sleep apnea is bad for you, increased risk of stroke and heart issues to name a few.  Then why 2 weeks to get back on track?    The process needs improvement  Other than that my Respiratory Therapist was fantastic and we had a good visit and got all my questions answered.   Thanks for listening.
