This machine is so small and easy for me to carry. I take it everywhere. Certainly makes going places much less of a headache for me. I’m thankful I found your company and for all you help. Thanks!
Very small and lightweight. I am very happy with the unit and it's weight. Easy for me to carry. Thank you for your help.
Thank you for all your help in choosing a system for my dad. The G4 is working great and he is more active than I have seen him for a while now. My family is so happy with our purchase and for all your patience and guidance. Thank you!
I am surprised at how small this unit is and how easy it is for me to carry. I am a small person so having something this small is really nice.
I really am enjoying my new g4. It is definitely as tiny as you told me. I like having an oxygen supply that is finally lightweight enough for me to manage. I do like that I purchased two batteries and being able to plug in my car, too. I'm very satisfied with my decision and thank you for all your help.
Not sure how long the battery is going to last, when I had 87%, it said battery low after about 1 hour. Will check it out more tonight. Other than that I like it !!!!
Great customer service, got a great price and item was delivered promptly
Just a note to tell you how happy I am with my Inogen G4. No one realizes how tied down one is with tanks and cylinders. This is so nice and easy! Thanks so much for being so helpful. Carey has answered some questions I had too and she is great. I can’t say enough about your company.
I really like my new G4. It's very small and I can just pick it up and leave my home as I do my purse. very satisfied thus far.
