    A year of ease 3 people found this helpful

    Bought my Inogen G4 in April 2023 for my birthday. Now that I have used it for a full year, I can give a reliable review. It is truly lightweight and much easier to handle and maneuver. It has never let me down. I called just for information about the Inogen G4 thinking I would not be able to afford it even though I had been saving up to buy it. It was a total shock that not only could I afford it but with the extended battery. It was unbelievable, I was so excited and happy I was in tears. It arrived in a few days. And I have used it every day. Everyone was so helpful and kind. They made sure the Inogen G4 would work for me and meet my needs. It has truly been a life saving life changing experience.

    Like it! 3 people found this helpful

    The gentleman I talked to on phone was very polite, easy to hear and understand, knew answers to the questions I asked and told me extra information which I was glad to get. I ordered what I thought I'd like and they had it delivered to me very soon and I have been getting acquainted with my new concentrator and like so many things about it--especially that it weighs less than another I had tried!
