"Portable Oxygen Specialist was extremely knowledgeable and very patient. He answered all of my questions and was not pushy. He also kept me posted of shipping and delivery dates. It was delivered via FedEx the next day! He also offered to help setup the machine. However, the instructions with photographs were extremely easy to follow to setup even for my father that was elderly and had limited vision. My father loves the machine!"

“We just purchased our 2nd Inogen portable O2 unit from Main Clinic Supply. The staff was very professional and shipping/receipt was very timely. We sent the old unit in for service and to have as an emergency back up and it was sent back the next day and in good working order. Great service!”

“This is the second Inogen oxygen concentrator that I have purchased from Ricky Gardea  with the lifetime warranties. He is very knowledgeable and professional. I have another Inogen floor model that I purchased from Inogen direct but Ricky is much better, at least for me. The service that I have received at Main Clinic Supply and it's delivery process (FedEX) is out standing. I can speak with over 12 years experience in purchasing and using oxygen concentrators.”

I really needed this portable oxygen system for the longest time. I finally made up my mind to get one even though they are expensive. I suffer from Asthma/Chronic obstructive pulmonary disease. I was always stuck in the house on my oxygen 24/7 and could not go anywhere or do anything. Your representative, Dylan, was excellent and very knowledgeable and because of his expertise, I was sold. So glad, Dylan helped me out regarding my new "freedom".

Probably the best company to order from I have ever dealt with.
Jeff handled my order and I would give him the highest customer service rating possible.
Everything was exactly as we talked about and the order came in less than 24 hours at no extra cost. Highly recommend this company.
