This company takes advantage of older, senior citizens of this country, and I would think twice before you do business with them. Listen on. The sales people over there tell you that the battery of the CAIRE SeQual Eclipse 5 Portable Concentrator, lasts 4 hours - for continuous flow. 4.5 or 5 hours for pulse. Neither are true. The concentrator only lasts 1.5 hours for continuous flow. A bit more for pulse. Then, because we had it for 12 days, we were told at first that we would only get a portion of the money back if we returned it. Then, the next day, we were told the unit was non-refundable. This is a HORRIBLE company, that lies, and just wants your money. We will NEVER do business with them EVER again. We are out of our money back, and are out of a concentrator. They take advantage of older, senior citizens of this country, and I would think twice before you do business with them.

The willingness of the OCS team to address questions and make suggestions to help lead me to the right concentrator unit for my needs. When I picked up my unit, they gave a very thorough overview of operation and maintenance. Very professional.

I learned something about canulas that I had never known despite using oxygen for a number of years. Need to be changed more frequently than I had been! Thank you.

Glad to hear you learned something new about cannulas, Elizabeth! They do need to be changed regularly to ensure proper function and hygiene. If you have any other questions or need more information, feel free to ask!
Drew Williams was very helpful in my purchasing the oxygen concentrator. He asked me questions of how I planned to use it and he recommended a model that would fulfill my needs. He was very professional and answered all my questions. His explanations were thorough. I was completely satisfied with the product he recommended. He had excellent customer service.
