They are big for overpromising and underperforming.
Bought their most expensive unit with all the bells and whistles ($4000). The idea was to be able to fly internationally. The first trip we took was actually by car, into Yellowstone National Park. my wife needs oxygen at higher altitudes (4000 feet or higher). The very first day at 6000 feet, the unit conked out. We were promised replacement within 24 hours. We called and they said they could not ship for another 2 days, they did not deliver on weekends (because UPS supposedly does not do weekend deliveries) and they refused to use FedEx. Suggested we check in at the nearest hospital at our expenses until they could get around to sending a replacement unit. Finally got a replacement after 3 days.
Sent back the broken unit for their analysis. They told us they would let us know the results, but never did. We contacted customer service and they told us that the unit was not designed to work at high altitudes (but they sure have it FAA approved for flying, which means a rating of about 11000+ feet, since most planes fly at least that high). They even refused to even apologize, but rather labeled us the bad guys. This company should not sell medical devices that peoples lives depend on. Bad product, lousy customer service.

I HATE THIS UNIT
I hate this unit. Your commercials says it is quiet and can go anywhere. My unit is so loud I can’t use it at night as it keeps me awake!!!! As for going out in public with it is so loud that it embarrasses to death. This was the worst purchase I have ever made.

Inogen took advantage of my mother and…
Inogen took advantage of my mother and sold her a whole new concentrator claiming it was much smaller and "better" than the one she had purchased less than 2 years before. When we, the family, found out that she has spent another $3000 on a portable oxygen system that was comparable to the one she already owned (from the same company), it was past the return period. We have had difficulty getting in touch with anyone to answer our calls or to be able to complain to. Of course, if you call the "sales" line, you are connected to someone right away, but they can't help us. Spoke to Customer Service as suggested below but was told "Sorry, it's past the 30 day refund period, we can't help you"

Fraudulent and Murderous Company - Don't sign anything with them!
Update on my last review. Inogen is preventing my mom from getting oxygen from another carrier.....she still does not have a portable oxygen compressor, which means she cannot go to the doctor without a transporter with oxygen to take her at $169.00 a pop. Now, they are saying she is not a customer, but she has a customer number.....
Inogen's corporate greed is slowly killing her as they diminish her quality of life day by day. We have contacted as many parties as we can think of hoping for some help, but it appears that corporate greed rules our society and as Bloomberg says, let the elderly die. I guess that Inogen is in bed with Bloomberg, they seem to have the same the mission statement...... It is hard to sit by and watch this happen day by day. Infuriating, heartbreaking, hopelessness, it is proving to be a very emotional time. We need to get her to her doctor, so because of Inogen we will be going to the doctor without oxygen because we cannot afford the transportation, we have came to the resolution that at least we will be in a medical facility and hopefully they will have some oxygen.
This situation proves that they are fraudulent as well, if my mom is not a customer, but has a customer, why does she have a customer number? Possibly to continue to receive the payments from Medicare and provide no service, which equals pure profit for Inogen!
My mom said to me today that if she dies, to please file a wrongful death suit against Inogen. Now how would you feel if one of your loved ones felt that way....and said those words to you?
Stay away from this murderous company, they will prevent you from getting the medical care you need. Oxygen is a matter of life and death.

I can’t believe that there is a 58%…
I can’t believe that there is a 58% good review here on trust pilot, unless inogen is making there own reviews like they erase all of the bad comments on their Facebook page. I did a review here a while back & nothing has changed, l’m on my 19th machine being delivered & every one of them continues to stop working repeatedly. Inogen’s response is to replace it with another machine that will quit working. My lungs have been damaged from these machines & no one within inogen cares, that is quit obvious from their responses. The better business bureau keeps giving an A+ rating despite the reviews & the federal trade commission doesn’t reply at all despite inogen’s false advertising & obvious disregard for their customers health. Please don’t let the rating fool you & read the reviews. This company is well aware of the problems with their G3 product & do nothing to correct it, they all need recalled, replaced with something that works &/or refunds given. Instead you get stuck with faulty equipment, worsening health from the faulty & then when your warranty is up, they’re not even going to replace them & you’ve just been screwed out of $2500 & 3 years of your life waiting for repeated replacements that will stop working when you are out somewhere. It’s really really mess up my rehab to get on a transplant list, otherwise they’re killing me.

I can only concur with the bad comments…
I can only concur with the bad comments of other frustrated customers. The salesman that mortified me was abusive and aggressive, he contacted my doctor to obtain a referral by convincing his secretary that I wanted the equipment. He told me that Medicare would not cover the equipment, which is FALSE since the hospital where my husband was sent a concentrator to my home the same day the Inogen arrived. I never open the box, I tried without success to return the equipment The website DOES NOT ACCEPT requests for equipment paid, THE STATED RETURN POLICY IS A LIE. I still have 2 weeks to arrive at the 30 days, where according to stated policy I would get my money less $99, and no one answers the calls. Only once I did get an answer, with the promise to get a phone call with the RMA, and this was ONE WEEK AGO, but no one called. Follow my advice and DO NOT DEAL with these people and spread the work to all our friends and the medical personal you get to know.
