"So far I can tell you that I love the device. It is more quite than my old remstar + M series. Our home temperature is set low at night and the condensation that I used to get in the hose from the humidifier would spray my face and wake me up, all the while not getting me the humidified air causing nasal irritation. The ICON with the thermosmart heated hose has been wonderful. The other features like the sensawake and the auto adjusting pressure I cannot really comment on. All I can see is that I am sleeping much better, and never feel like I am getting too much or not enough air. I do not know if that is attributed to the sensawake or the auto adjusting pressure or both, but I know something is making me sleep better. It also packs up and travels nicely. You do not have to remove the humidifier and all that stuff to pack it away for travel. This also was an important feature for me. I have only had the machine for a week now, so I cannot comment on it's reliability."
