High-performance 1-7L Concentrator Machine, 24h Continuously Oxygen, Low Noise with Remote Control

Read the how-to book, set it up and turned it on in less than 5 min! My wife needs a oxygen concentrator odd times of the day as well as sleep time. We camp and travel often so we needed a portable device that is compact and is able to plug into multiple voltages as well as 12 volt. So far so good, appears to be a well made machine.

This unit worked as it should.

I am very thankful for the help of this amazon seller's customer service, they are able and willing to quickly help me with any issues that came up, and quickly respond with good customer service. I highly recommend them.

I am on oxygen at night and needed a good portable machine. This is it!!! So happy with this purchase and the value. Paul has been great to work with. :)
