FLORINE V.
Thank Heav--ens for In--o -Gen! (To the tune of "Thank Heavens for Little Girls".
I greatly appreciate Inogen One as it is a convenient way to transport oxygen; it is by far, one hundred percent superior to the previous method I was using. It would be advantageous to be able to change batteries on the G4 model without removing it from the bag. The bag fits well but it is a struggle to get it on. The G3 model is so much easier to use, but it of course weighs more, and that is why I bought the G4.
