First 2 numbers of serial number indicate year
I had a 2023 Inogen G4 that stopped working. It was going to take 4-6 weeks for repair. I saw the OxiMedical ad online. Spoke with Gordon Moore on a Saturday he said I could do a trade in and get one by Tuesday for $997. I was desperate for a portable concentrator. I asked how old would the used one would be. He said they didn’t sell used ones and it would be last years the last year the G4 was made. I went ahead and took what I thought was a reasonable deal. Not a major thing but he neglected to tell me there was a $29 shipping fee. He said he would refund that. My unit didn’t come on Tuesday as promised. Then he was going to try to get it delivered Wednesday morning, I waited all day on a delivery because I was supposed to hand the driver my G4. When I get the G4 from OxiMedical it was a 2017. I gave $1000 and a 2 year old G4 for an 8 year old 2017 that Gordon said was Certified, Be ware of any fast talking sales person. I looked on line for those of you who might want to check anything bought from Oxi Medical the first 2 numbers of the serial number indicates the year.
