I don’t like that one took to long to get my unit. Your unit is to noisy for someone with hearing aids. And finally the people we spoke to very seldom returned our calls when having trouble getting my unit originally . Your service needs a lot of work

As soon as we got it
The standing unit is loud and makes it difficult for me to sleep. My husband, who the oxygen is for, is hard of hearing, so it doesn't bother him. When I talked to customer service they told me, there are no techs that check on or work on devices. That's a problem for me. I have problems with my hands. My husband will continue to use the unit.

I have had my Inogen G4 for 2yrs
I have had my Inogen G4 for 2yrs. I was told by Inogen rep it could be used 24/7/365. Dr. has said the machines are not able to stand that usage, lied to. Inogen has had to replace my unit 9 times in 2 yrs, low oxygen, they just stop running. Inogens imo are the lowest quality product on the market today. Warehouse is closed on weekends and holidays can't ship. Save yourself the frustration, walk away from Inogen.

Today is October 2nd I have been trying to get Oxygen Equipment through Inogen since early August. Once again today I was on hold several minutes but at least now I have a number where every 3 minutes of musak doesn't result in being cut off and having a dial tone 5-6 times in a row. But of course I was told that my order was being reviewed and it might be approved today and sent to shipping. If so then shipping has 10 working days to ship out and I won't be notified of anything until shipped. So I will again go through the phone hold in 2 days so I can bird dog this company to see if there is any action. If you choose to use Inogen good luck and attempt to bird dog your order.

Inogen has a great mchine G3 which has servived me well.
However, it is 5 tears old, and they no longer service.
They send you to Main Clinic Supply which requires you to take a lifetime warranty and costs close to $1000. i think that is excessive and gives you no alternative except to buy another machine. I think they know this and it is part of their business plan.

A Caveat if you Rent...
I've rented through Medicare for approximately 8 years.
This company was wonderful for the 1st 4 years, excellent equipment & A+ customer service. No longer are they even slightly customer oriented.
If you rent through Ins. Or Medicare they give you NO choice of machines. Unlike the 1st few years, machines are refurbished & not always reliable.
Remember they receive Medicare + your supplemental Ins. Payments monthly. In 8 years mine would have been paid in full years ago so INOGEN is making much more on rentals than sales.
My latest Experience: I had an Ever Flo as my floor/home oxygen for 7 years. When it malfunctioned I was sent an INOGEN Home. Very nice small & quiet machine, however, although it can be set on levels 1-5, it cannot be set on the 1/2 or 3/4th's so no in between which doesn't work for me since I use 3 & 1/2 or 3 & 3/4.
So they replaced that with a Drive - large, heavy, loud & my oxygen level dropped several points.
Again I asked for Ever Flo & was told I do not get to pick, so, they sent me the INOGEN HOME AGAIN. Doesn't work, please send Ever-Flo. Nope, you're Medicare so no choice. They sent ANOTHER DRIVE!!
We sent it back, unfortunately without unboxing.
My husband took me in my wheelchair to see the DRIVE we had & I realized it was a dangerous refurbished that had NOT, in my opinion, been refurbished at all. The door to the filter was missing, the filter was a blue, see through plastic with FILTHY dirty white fan/filter inside that was no longer white, it was a used dark gray.
My husband couldn't get the water bottle on because that was either broken or had a part
Missing, we gave up.
I called INOGEN waiting the usual 15-20 minutes on hold for an agent.
I was told I must keep the broken machine. I wasn't happy with what they sent - 4 machines but actually 2 of each, neither useful to me.

I purchased my inogen one 5G Nov 2019
I purchased my inogen one 5G Nov 2019, the problem I have is that I just got my 10th replacement today, what really upset me was that June 30, 2022 it stopped making oxygen, I called customer service, they sent me a replacement July 1, it stopped making oxygen July 2, I called customer svs and they told me they closed for the 4th July, I called them July 5 and they would send a replacement July 6, I told them my wife was having heart surgery July 6 and they said that they couldn't get it to me the 5th, when I received it the 6th July it was the wrong unit it was a G-3, I findly got the right unit July 7, 2022.

Disappointed.
So the financial outlay does not end with the initial purchase. Expect the columns to go and the batteries...of which ...neither are cheap. I'm sure you were told to keep the batteries charged all the time..right? Let's screw the elderly.
