  • Outstanding!

    I danced with the idea of buying the Z1 or another portable device (out of pocket) for a couple of months; what helped make the Z1 decision was the no return hassle if not satisfied plus some videos on You-Tube. Are there still concerns for me, there are, for example will the battery last the night & the enclosed humidifier does not seem to fit on my mask. What I am very unhappy with are our Royals, geeezze guys!

  • EverythingI wanted

    I wals looking for a small, very portable, quiet CPAP unit that was able to use my hose/mask combination. Z1 provided everything. My only issue was it came with factory settings and I needed more air. The customer service staff emailed me a one page sheet with all the instructions to change the settings. Provided quality sleep once I changed to the correct settings. It is momentary makes slightly more noise while it is calibrating my inhale/exhale requirements, but after a couple of minutes it is silent. Fine product, and with two batteries I'll never worry about having a long term power outage. I'd recommend this system!

  • Wicked Little Machine

    The Good: Really small. Even with the battery pack. A battery easily lasts a single night. Instructions on set up are easily followed but would like more explanation of a couple of the functions. Bad: When breathing in, this squeals like a stuck pig. Is this normal? I put the machine under my to block the sound and that helps...but wow. The air flow howls like a hurricane. I tried a larger diameter tube and still the same howl. At 4cm during the ramp this is much louder than my regular machine at 9cm. I have ordered the muffle and will see if that helps with the howl and the squeal. I have not been able to connect to the machine with either my phone (Droid Turbo 2) or one of my laptops (HP). I need to try my iPad and other laptop (Dell M7510). Wait and see: I got the inline humidifier muffler and it is hard to see if it works. It needs a rubber connection on the larger side (other side goes into the rubber connector of the tube) instead of the hard plastic...which connects to the hard plastic of the mask. A way to charge a battery external to the Powerpack would be nice; particularly since the deal right now is an extra battery for free. The carrying case is an abomination. Any advantage to the small size is negated by using the carrying case (that cost $35). Overall: I do not have any issue removing either the battery or cpap machine from the powerpack. Seems pretty straightforward to me. I will keep the machine but need ways to mitigate the machine noise (headphones?) and find a better carrying case.

  • Does the job, but somewhat noisier than a full-sized machine...

    Works as advertised... but be ready for a somewhat noisier experience - worth it, to me, for the convenience and small size.

  • Nice size

    Keep in mind that the max setting is 20. Also, the unit is very noisy. My wife complained. Even with the inline noise device installed. So...I returned the unit.

  • Sleep Tight

    I hated having to lug my CPAP machine with me on trips. Finally came across this traveling CPAP and WOW is all I can say. Its small, light weight and packs a powerful punch. Didn't think I would get the same sleep quality with this small machine but I do. Would recommend to anyone that travels.

  • Europe or Bust

    Lightweight, compact & perfect for travel. I used in for a week in Europe with my family this summer and it was a lifesaver in hotel rooms. I slept and so did everyone else! Wife could hear the noise of the machine (or the mask really) but much better than my snoring (or so she said!!!).

    I thought it was quiet through the night and was quiet and my wife remarks at how quite it is and the battery packs keeps me going throughout the night and one of the best yet I have used so far!

  • Too Noisy!

    I really wanted to like this machine - it it compact and easy to use. Unfortunately it was so noisy I literally could not fall asleep while using it. It wasn't just white noise, but pitched noise which slid up and down the scale as I breathed, and was rather like trying to sleep with a harmonica in my mouth! Fortunately has a generous return policy, so I will be trying a different compact machine and hope the noise level is less.

  • Great concept

    I can sleep through a raucous football game. I cannot sleep through the night with the Z1 unit. It is extremely LOUD! Otherwise the idea of truly portable CPAP unit is the only redeeming feature.

  • Loud

    I love the size of the Z1 Auto cpap, however the Z1 is so loud and it is so hard to fall asleep while in use.

  • Cool for Summer

    I bought my Z1 and it came with the new qTube muffler. It's very quiet with the qTube and I'm lovin it for camping at the lake this summer. I might get a qTube for my bigger machine too.

  • Small but noisy

    The size of this APAP makes it great for travel. However, it is a compromise -- noisier than my regular CPAP and I do miss the humidifier. Better than nothing when traveling.

  • Excellent for travel

    Purchased this unit specifically for long International travel (10 hour flight). Received two days prior to departure and had no trouble adjusting to use compared to F & P Icon which I use at home. Much easier to travel with and worked with aircraft electrical system with no problems. Easily stored in laptop bag vs. carrying an additional bag for CPAP as have done in past. Recommended!!!!
