I had been using a mask, that was waking me up at night, to stop the air leaks. So I saw this mask, liked the design of it...and decided to finally make a change. I love the strap placements on this mask and also the small nasal coverage (not blowing air into my eyes, for instance) The side straps are very slim, and with the soft wraps included to cover them, I have no strap marks. (just make sure that you do not make them too tight.) I was worried that since there were no straps below the ear and across the cheek, that it would slide out of place...and it didn't! I am getting a perfect c-pap treatment now (I also upgraded my machine...so I set to go.
