I wish that I had known that the machine is not very quite. If I took it in church I would disturb others.

It is a little heavy but it works. I wish it would work with my bpac machine.

While my Inogen One allows me to have oxygen on the go, it does not last more than 30 minutes on setting 4. So what use is it if I am traveling and the trip is more than 30 minutes? Or I get stuck in traffic? Or any number of other things. Reading the information booklet and seeing all the ads induced me to believe that the battery lasted longer than that, so I only ordered the single battery. Since you can ONLY charge the battery in the unit, another important fact that was left out of the documentation, I am SOL if I don't have a car or an electrical plug available. And I can only assume the double battery would only have a 60 minute lifespan.

Like fact that unit is portable but it only goes up to 3 liters & I need 5 or 6. I use it only to do short errands or visit friends & out to eat. Good as long as I don’t do anything strenuous. Dorothy Nordone

I found that I cannot take it into restaurants or theatres because it is so noisy, Even my doctor said it was too loud.

The machine makes too much noise. The battery does not last long enough.

It makes to much noise.I have one and don't use it.

Batteries do not last as advertised. They only last at the lowest setting on your claims???
