I had to call Snap to register when I got home with it. They wanted a credit card number for my portion, and said whatever the insurance paid or didn't pay, my max would be $250. My high deductible insurance didn't pay anything, and sure enough about a month later I got a charge for $250.
I wore it three nights, carried it back to the doctor, and got my results in about a week. AHI of 39. Diagnosis and RX.
The RX helps a lot with ordering equipment, even masks.
