    Easy enough for a 95 yr old 0 people found this helpful

    Didn't research a lot, just knew I was tired of the oxygen canisters. The oxygen concentrator has not only made my life easier but my 95 year old mother-in-law. She now has oxygen as she goes out of her room to visit others and eat her meals. Then when we venture out, our time is better spent together. When the machine is set up she only has to push the on/off button. TOOOO EASY!

    Great service 0 people found this helpful

    Great service, package arrived on time. Only real complaint is the battery life, unit only comes with smaller battery doesn't really last 2 hour's as I was told. And with a 2,400.00 price tag honestly both size batteries should be included in the price of the unit. Not a almost 600.00 increase for a larger size battery.

    Best experience ever! 1 people found this helpful

    Best experience ever with a supplemental oxygen source. I was looking for a replacement for Apria, Kaiser-Permanente’s supplier, and was bowled over by the professional, friendly and helpful staff at The Concentrator Store. I bought a Inogen G4 concentrator from Matthew Schock and it was a great experience. When I went in for a warranty service I was treated so well by the receptionist and service department that I couldn’t stop talking about it at dinner with friends. I won’t go anywhere else.

    Carry case 2 people found this helpful

    The unit is fabulous, the carry case is not. I was hoping they would design a new one with 2 handles.

    Fantastic equipment and wonderful service 1 people found this helpful

    I was extremely pleased with Jake's knowledgeable, helpful and friendly service with the purchase of the Inogen G4 for my Mom. She was newly diagnosed with a need for oxygen, and I must say, the portable convenience and light weight of the G4 is perfect for her. Jake made sure we received everything in a timely manner, and made the process of purchasing this equipment easy. I definitely recommend The Oxygen Concentrator Store, and enjoyed working with Jake. With the Inogen G4, there is no need for cumbersome oxygen tanks. Truly, it is the only way to utilize oxygen!
