I am on my 6th G4 Unit less than 2 years
I Purchased a portable G4 from Oxygen Generator Store/AMSR,Centennial, CO in July of 2024. In Aug. 2025 it kept shutting down-System Error). Had to pay $195. for a refurbished unit. It continued to shut down for the next year. I am on my 4th unit this month. (July,2026) System error or system hot. (now we're up to 6 total) They send a reburbished unit and it shuts down the next day. I regret I didn't record serial numbers-am I getting the same machines back? They are now testing the 4 refurbished G4 units they have in stock and will call/send me the best one-they'll call on Monday. Buyer beware.
Note: I did purchase the Inogen Home about 7/2024 direct from Inogen and it works perfectly.

I would have Zero stars but Not an Option
So.......after seeing commercial I called,
Here are the scenarios that progressed
Knowing advertising is just that, I inquired about the under 3 lbs as shown in TV
I was told.......for PURCHASE ONLY
ANY LEASING 4.8, 4.9 AVAIL ONLY
THEN GIVEN DIFFERENT QUOTES, Cuz DocuSign and docs with bank card on file must go through to lock in rate
Then told to bother doctor, they too lazy or can't be bothered to reach they don't NEED IT, then told by a gay sounding he said was supervisor, they have No Reps in NEVADA"
I assume an excuse for shabby service to say the least, then called company a few times in which I was hung up on, didn't appreciate my blunt candor of shit business operation.
As I watched commercials even more
I saw in fine print........
"ACTOR Portraying WHAT A LINCENSED AGENT MAY SAY"
I GUESS THATS HOW COMPANY HAS LOOP HOLES OF PATIENTS ORDERING A UNDER 3 LBS AND SENT SOMETHING ELSE
Then I was called by an agent laughing hysterically that it takes so long.
Well a company who has $ for commercials, it's actors that scam the public, shit agents I guess dissatisfied with pay or whatever? Has the money to just cater 2 those who can pay cash........agents say.......inogen NEEDS A COMMITMENT, EVEN IF LATER Dissatisfied STILL HAS A CONTRACTUAL OBLIGATION WITH MEDICARE FOR 5 YEARS.
Yes I was ALSO TOLD THAT ON THE TRY IT FREE FOR 30 DAYS AND TOLD ONLY AVAIL ON PURCHASE WHICH I SERIOUSLY DOUBT AS WELL GIVEN ALL OTHER Circus PERFORMANCES TO STICK CUSTOMERS WITH EQUIPMENT THAT AGENT FAILED TO GIVE PRECISE CHARGE AMOUNT TO MEDICARE JUST 20% OF THAT EQUALED TO UNDER 30.00 A MONTH
Total cost of without warranty was told to be 3600 dollars, what a RACKET ON EQUIPMENT ONE WOULD THINK AGENTS WOULDNT BE SUCH BOTTOM OF BARREL
PERSONIFICATIONS UNLESS MIMIKING THE OVERALL UPPER CHAINS AND CEO OF INOGEN......
Well an opinion formed on experience.
Then I read something someone else said high up front cost, maybe why THEY WANTED A BANK OR DEBIT CARD TO EVEN DO ANYTHING. YUP.
STATED CLEANING PROBLEMS, I GUESS FOR THE COST SOME MAY EXPECT IT TO CLEAN ITSELF, NEVER THOUGHT ABOUT THAT NOR WAS INFO ON SUCH VOLUNTEERED
Also review says date of exp. But as stated earlier AGENT THOUGHT IT HYSTERICALLY SAYING I KNOW TAKING SO LONG. WELL OVER A MONTH, Another said 1-4 weeks after approved. Yeah.......been more than that just in process "SO CALLED"
ONCE AGAIN...............FINE PRINT DISCLAIMERS ON TV SHOULD BE READ SO TO TRY AND ASK.............ESPECIALLY HOW ABOUT ADS SAYING AS SEEN IN TV
DOESNT STATE ACTORS PORTRAYING WHAT AN AGENT MAY SAY TO A CALLER

Customer service is horrible
Customer service is horrible. You wait on hold for at least 20 minutes only to be routed to someone else and then to someone else. Then only to be told Inogen won't service your unit because you didn't buy it from Inogen and No, we don't have any authorized representative. I also had rental equipment, and they back charged me for over a year because they said they didn't have authorization to charge me before, even when I asked the year before why they were not charging me and was told it was probably because I had already paid for the equipment. When I questioned the bill I was told if I didn't pay the full amount I would be turned over to collections. DO NOT USE ANY INOGEN PRODUCTS if you want customer service.

Inogen Rave 6 Bluetooth app can't change O2 out or even turn off the machine without actually physically manicuring the change directly on the device. These 2 simple options are considered programming 101. Here we go Turn on the light! find the bulb, take off the shade, screw in the bulb, Reverse process to turn it off. GENNIUS Stuff

Lifetime Guarantee is useless.
The Inogen portable oxygen was purchased with a lifetime guarantee. It is broke. Called customer service, they are wanting me to buy parts to repair it. Guess what, the part just happen to be on sell. Spoke to two people who will not honor my lifetime guarantee. The cost of this machine was double what I could have purchased other brands but we choose this one because of the guarantee. Sent a email to their office. Hopefully, someone will fix the problem.
