I have used another Brand for many years, and when I was changing, I bought the same one (from abroad). This time I called the CPAP center and told them I was having some problems with my old device. Thanks to the CPAP Center, they took care of it very well and professionally. I decided to buy Resmed Airsense 10 Auto CPAP and it arrived quickly. I felt the difference in the first night and fell into a deep sleep. When I woke up in the morning, I felt very good after a long time. For me the result is important, Wifi, Bluetooth etc. It doesn't matter, the important thing is that I sleep comfortably and fully and wake up fresh. If I can't find a cure, what should I do with the latest technological applications? I am very satisfied with Resmed Airsense 10 auto CPAP tool and recommend it to everyone. I would like to thank the CPAP Center team for their service and respect.
