I bought a 2000.00 concentrator that began to give me a low 0/2 indication with a beep, you couldn’t reset it! They sent me a label to ship it back and we did! In the meantime I ordered a small concentrator 1-7 liters, they billed me for two and sent me two. On 7 liters they only raise mo o/2 to about 84 I have another concentrator and on 4 liters my o2 is at 92-93 the small ones don’t work. I ordered a battery for my portable concentrator it was almost 300.00 and a new 18 cell battery. When it arrived it said to charge before using I went back to my office after a few hours and it was flashing red indicating a bad battery. The sent me a label to send it back. In the meantime the original concentrator was returned , we plugged it in and were astounded it sounded like a tractor. This was supposed to be the top of the line and quietest 1-10 liters on the market. My wife slept in the living room, I went to sleep and awoke around 1:00 am I couldn’t go back to sleep so I downloaded a decimeter on my I phone at my head laying on the bed the decibel level was over 85 that’s louder than a lawn mower and it was suggested that I wear hearing protection. At the machine the decibel level was 91decibles. They sent me a label to send it back. I have asked for a new machine, we will see what’s next! It’s about time for some legal action to recover my cost and inconvenience!
