I haven't tried this type of mask, but my sister had suffered from breathing problems during her sleep for the past few months. It was creating a lot of trouble for her. So when we took her to the doctor, and he suggested a detailed checkup. While going through the result, he told us that she is suffering from sleep apnea problems. He suggested buying this ResMed AirFit F30i CPAP Mask for her. Finally, we bought it for her, and she started using it while sleeping. We were able to see a tremendous change in her after using it. She can sleep peacefully now without any issues. While talking to her, she has a positive response about the mask since it doesn't make any trouble to her while sleeping
