Very pleased with the oxygen concentrator. I have it at my son's home , where I go regularly. It is wonderful to know that I have a quality machine there to take care of my needs.

Thank you for your order!
We bought a used O2 concentrator and found that the support personnel were very helpful in explaining a) what had been refurbished, b) how the device worked, and c) generally giving us a good feeling about the purchase.

Thank you!
I was sent a machine that did not function as advertised, and the wrong charger for it. I paid freight twice, one time to send back the wrong parts and the other to send back the poorly functioning machine. They returned the machine still not working properly with no explanation. I would give them zero stars and recommend no one do business them. I am stuck with the cost of the machine, two freight charges, and a machine that will not work properly.

I am truly sorry you feel this way sir. Our records show that your complaint was about the battery life not lasting as long as you thought it should. It appears we have already sent you multiple batteries and a replacement charger in good faith, but you were still not happy. This is when we decided it was time for your unit to be sent to us for evaluation after you have been using it for 5 months. As described in our terms of service, the customer is to pay freight to send their machine to us, so there was no surprise to be had. Upon testing of your unit, we found the chargers working properly, the battery life was right at 45 minutes at 2LPM Continuous flow after being fully charged and depleted. Absolutely everything seemed to be working as designed, so we packed it up and returned it to you. There was a packing slip on the outside of your box that detailed what work we performed. It is possible it came off in shipping.
Arrived in a timely manner and in good condition.Surprised how nice it looked even though it was used.
