This unit was suggested to me after I wanted to buy the Z1. I travel to rural Mexico a lot for work and I have had situations where I don't have access to electricity. I also bought the multi-night battery.
The machine itself is small and light. It's pretty simple to use but once you plug it in, there are indicator lights that flash for a moment and then it appears to be off. It's not. You will also get a green light indicating the power is good whether it is or isn't.
The sounds of the machine mimic your exhaling. At least while you go to sleep. IN the middle of the night I heard a very loud air sound that was just solid, not related to breathing. I thought maybe there was a leak but i moved the mask and a leak was a very different sound. I thought maybe it was responding to a blockage but I was awake and breathing so there was no problem. Maybe it's just a different sound the machine makes at one point. I would turn it off. Wait a moment and then start it again and it would again mimic my breathing. Other times I would wake up and it was almost silent.
(I described all this to a rep at [Supplier #1] who said it was normal but she wasn't really listening to me so who knows. I have to believe this is how the machine is intended to work but i'm not really confident.)
The multi night battery worked for a night and a half. I do not recommend it. When I asked about this I was told it depends on a lot of factors. As Judge Judy says, DOn't pee on my leg and tell me it's raining. It's multi night or it isn't and this isn't.
The machine may be good. The battery is not
