I bought one of your inogen a couple…will never buy another one
I bought one of your inogen a couple years ago I bought every acc. Plus 2 extra batteries.it worked good for a couple years then it displayed an error I called and they sent me a new one. Within a short time it displayed the same error as the first one.i called this time I was told I didn't buy a warranty so it was going to cost me almost $1400.00. so I bought another brand and it is working good. I will never recommend
or buy anything inogen. Ps.i was never told I needed to buy a warranty on the second one . You thank me for the review but not a word about sorry for the inconvenience you created.i lost all faith and respect for your company!!!

"PORTABLE" INOGEN TOO HEAVY TO USE
My "portable" inogen is too heavy for me to use; I don't know what it weighs. However, I'm 83 years old and weigh 100 lbs; I also have torn both my shoulders' rotater cuffs and have other health problems.

Find a different brand with actual customer service!
83 year old mother in assisted living has been without her machine for over 6 days. They came and picked up her old one for repair but left her with one with no battery nor charger. Still can't get a hold of anybody. I will not recommend this product at all! everything says just to call them and like everyone else says, you are stuck on hold for over half an hour and then you get disconnected. Find another brand

These canulas will be kinked up in less than 24 hours.
I told the girl that these canulas would not fit, but she assured me they would. Nope. Would not fit. In trying to make it fit, I was afraid that I was going to break it. Thank goodness for wonderful neighbors. My medical neighbor came over and with his medical knowledge he was able to change it, but it is a temporary fix. It is not his job, but he is going to make some contacts and get a proper fit. Okay. Canula is connected. I put it on and the oxygen is flowing freely. I could tell the biggest difference. It has been less than 24 hours, and this canula is kinked up worse than the old canula I had been using forever. So that was a waste of money, but I ordered 10 from Walmart for $12.99 and free shipping. They work great. I will never do business with any company who cannot provide service. To me, over the phone service is NO service, and that is exactly what I got--NO SERVICE! I paid $4,500 for respiratory equipment, and for that amount of money I expect some real service. I have more than enough health problems and do not need to be bothered with all of this. I received an email from Inogen telling me to call Customer Service at this number so they could make things right, and that girl was so incompetent I had to read her the reply. She said it was an update and to not pay it attention. So once again, no help from Inogen.

Not working well 4 hrs O2 with backup battery
The products did not make oxygen for 13 hours even I was getting maybe four to six then it crapped out completely I was too busy to call you however I did speak to a person and told them it was broken and never heard back from indigen it was very expensive so I would have expected somebody to call me and give me the process to return the product and have my money sent back or get me a new product but that didn't happen

I obtained the Inogen One via insurance…
I obtained the Inogen One via insurance because I was impressed by the TV ad. And found the product is not as advertised. One, the battery does not last any longer than two hours (Not six), and it will not recharge while in use. Once the battery overheated. The battery was replaced, and it has the same problem.
The in-home machine has also been replaced because it stopped producing oxygen and emitted a white substance. The replacement machine. The alarm on it is currently sounding. Customer service provides the worst service ever. I've been forced to argue with the representatives to convince them that I need another machine due to a malfunction. One said the machine is working even though the alarm is sounding. and refused to send another machine at first.
The equipment is faulty and worthless. The company, in my opinion, is even worse.
