Stellar customer service, I could not ask for anything more. Easily the most worry-free and competent thing I have had to deal with since my father was hospitalized with pneumonia and a pulmonary embolism. Will definitely recommend.

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.

Helpful and honest recommendations from Rex. Purchased G5 which became loud over first days. G5 replacement handled efficiently. New machine is great. Phone calls / questions post purchase are answered quickly. Will highly recommend this organized and responsive company to others.

I had need for a Oxygen concentrator, Bret Bennett was the representative who assisted me in purchasing the Concentrator. Living in at a mile high I needed a little Oxygen while sleeping at night. Bret walked me through in choosing the right concentrator for my needs, quite, small footprint light enough to move when needed. Bret also assisted adding in the necessary supplies/Hoses etc. needed for a complete concentrator system.
