Z2 Auto Ultra Portable Auto-CPAP Machine Package
i've had a z1 for a long time. it always looked great, but i wasn't particularly happy with the noise levels. i figured i could try the new one risk free so why not give it a shot. the new machine feels a lot better than the old one - more sturdy - and it definitely sounds quieter. there is still a noise so you know it's on but it's not much different than my home cpap. overall i'm very impressed. the manufacturer name on the unit has changed, so maybe they got bought out?
