hehe love/hate. I used to resent mine at times but not anymore. The only time now after 13 years of having it that I have any negative feelings toward it is when the power goes out and I can't sleep! LOL
Despite living on the edge of the city our apartment complex seems to get allot of power outs and those momentary flickers that are just enough to mess up clocks, turn off computers etc.
Since we do go camping or anything to justify the cost of a battery backup for CPAP. Having one for the maybe 2 hours tops we have no power every couple months isn't worth the $$.
Oh yea on the strap marks on the face. I found that if you take a reasonbly thick handtowel. Wet it and heat it up in the microwave and do an old fashoined hotsteam face wrap the marks go away MUCH quicker. I recently changed masks too and that helped imensely as now I don't have to wear the new mask near as tightly as the old.
FlexiFit HC407 Nasal CPAP Mask I wish I woulda had this mask 13 years ago!! It is so comfy.
