I love this little guy. Very portable and I with an external battery I can use it on long airplane flights. Very compact.
I would give it five stars except for a couple of points. One is that the placement and "feel" of the control buttons is not well thought out. Second, if you have to readjust your mask, the CPAP shuts off very quickly and so you have to fumble with the aforementioned poorly positioned buttons. A third point is that the machine sometimes just shuts down in the middle of the night for no apparent reason, and again, fumbling with aforementioned buttons.
