Okay. I made a mistake. I was so sleep deprived. I should have reviewed the Cpap Store not Resmed. The myair. Resmed machine is okay. The machine works okay for me. It was a big rip off to to medicare though. I was able to buy a new one for my son for $500 without a doctor. My issue is the Cpap Store. Never do business with them. They made a lot of money for nothing. I now get my masks and supplies from Linncare. They are wonderful.
