Earl, you will love it! I think my setting is 9, at first I used the 'ramping' feature that allowed the C-Pap to gradually get up to the pressure that you end up with. I don't need that now. Also the one with the little pillow thingys comes of very easily if you have a bathroom emergency. My sister has that huge whole nose mask and she has to completely undo everything. But hers has a heated coil running through the supply tubing. I think that would be nice. Good luck with it. And remember to take it with you even if you go for one overnight.
