“This is probably the best mask I've ever had, and I've tried a lot of different ones over the years. Although it's not perfect, it's been thoughtfully and cleverly designed from the user's point of view, solving a lot of the problems that plague CPAP users. Its best features are (1) it has a swivel hose attachment on top of the head so there's no dragging as I change position, and I'm a restless sleeper so this is really important. (2) If I get the mask adjustment just right it's almost silent - no whistling of air and no cold air leaks blowing into my eyes. (3) It's lightweight and comfortable whether I'm lying on my side or my back. (4) It doesn't leave indents on my face in the morning.”
