    I love the price and I love this unit! Very easy to use and lightweight. – Sam

  2. Oxygen Always Reviews

    My wife and I bought an Inogen directly from the manufacturer, paid over $3000 with a lifetime warranty and then her needs increased. Oxygen Always took my unit on a trade-in and sold us the G3. I wish I knew then what I know now. – Calvin

  3. Oxygen Always Reviews

    I dealt with Inogen directly and was shocked to see how much they sell their units for. This was almost half the price! I am grateful my husband and I can travel again! – Sharon

  4. Oxygen Always Reviews

    I paid half the price for the same unit sold by the manufacturer. We can now finally go visit our family and friends! – Chris

  5. Oxygen Always Reviews

    My husband uses 4 pulse and we needed a unit that went at least up to 5. I wish there was something lighter, but I am grateful he can get out in the yard again. I would recommend this product and company. – Carrie

  6. Oxygen Always Reviews

    I would rate this 6 stars if I could. This portable is so much better than the tanks. I can travel without relying on my local outfit to ‘hopefully’ provide something. I have freedom again! – Betsy

    Very lightweight and easy to use. I wish I knew about this sooner! – Jared
