our previous sales person Mars was able to point us to the right portable machine previously. We needed another machine to connect to the cpap machine. He sent the right connector and it works great. It was delivered in 2 days.

I took my portable oxygen up the mountains to 8000 feet and it worked great to help me breathe when my oxygen level got low especially at night. Living in Colorado it is a must for being able to enjoy the mountains again without worry

The sale with Rex was great, the after I paid and had a product concern did not, I have received no response from Rex or the sales team! I e-mailed a few times. I wrote on 15 Nov 2022 "received the equipment today. Charged batteries full, tested the unit, but I get alarm # 4 on and off No breath detected. I checked the cannula and no problems there, I used it instead of my wife as a test and same issue, anything I can do to fix or adjust this alarm condition. When she is using it her O2 is 97-99% so I know it's working correctly."
