Kazel, W.
The unit you shipped did not work. They want me to pay for the return, then they will inspect it and consider sending a replacement or refund. Their front office talked to the shop and they sorted out their communication problems. I then received a good new unit and a full refund.

Thank you for sharing your feedback, William, and we are truly sorry to hear that your unit arrived not working. That is never the experience we want for our customers. We did reach out to you to help resolve this but unfortunately were unable to connect. We also want to clarify the options we offered, as we want to make sure the process is as easy as possible for you. 1. The first option is to return the defective unit, and as soon as we receive it we will ship your replacement immediately at no cost to you. 2. The second option is that we ship your replacement right away, and we simply ask for a refundable deposit in the meantime. Once we receive the defective unit back, your deposit is returned in full. You chose the second option, which is why a deposit was placed. Regarding the shipping charge, that was a UPS pickup fee for having the unit collected directly from your home. We would still love to help get this resolved for you. Please give us a call at 877-303-9289 so we can make sure you end up with a fully working unit as quickly as possible. If you ever need anything else, feel free to reach out, we're here to help!

Great sales man that knew what I was looking for and gave me a great price. No need to haggle the price, gave great savings right off the top, even threw in ten extra cannulas at no extra cost to get me started, this was beside the one that came with the G6 concentrator

Mr. M.
The rep at OCS provided lots of information about the handling and care of the concentrator. Delivery was relatively fast. I would highly recommend Oxygen Concentrator Store for any purchase of a concentrator.
