  1. Edward

    The unit is fabulous, the carry case is not. I was hoping they would design a new one with two handles.

  2. Corey

    So small and easy for me to carry. I can’t carry anything too heavy over my shoulder and this works great. I did take your advice and wear it around my waist like a waist pack and that works really nicely too. Jeff took so much time with me answering my questions and I am very grateful. Great company and great product.

  3. Stans

  5. Donald

    After hours of research, and calling several online companies, I think the the G4 from Portable Oxygen Solutions is the best portable concentrator for me and my needs. I got a great price and excellent guidance.

  9. Matthew

    I am impressed with how small my new G4 really is. I guess it only weighs about 3 to 4 pounds. I am able to carry the G4 anywhere I go and that’s very nice and a big difference from the tanks I had. I am very satisfied that I got the g4 from you and thanks for the discounted price!
