Re: me50's question about "for her" capabilities... We have both models at our house... the "for her" has the same capabilities plus the addition of "for her" mode. Pressure ranges and data collected are the same. Algorithm that decides how to adjust pressure is different in "for her" mode, but the "for her" machine is switchable between "for her" mode and regular mode.
There has been a fair amount of discussion on the forum about "for her" capabilities. If you want to check it out use the following google search link (the forum search rejects the search request due to keywords being too short)...
If the sleep clinic has convenient hours and location for you to drop by in person, that might be helpful. Show up while the doc is in the office even though you won't expect to see him in person. This way you are sure to walk away with the proper prescription in your hands versus potentially receiving a screwed-up script that can't be fixed until the doctor comes back in the office next Wednesday.
good luck and be persistent,
