In the last three months my G5 has stopped charging while we were away from home. The second time was a unit Inogen had just sent me due the failed one I had sent back. Thank goodness I purchased the lifetime warranty from a financial prospective, but not from a safety prospective. Inogen needs to do a better job fixing these machines so folks feel comfortable using them away from home. They’re a good company and can do better!

The machine works fine. The carrying case is the problem!!! Not enough air flow and the battery still gets hot!!!!!!! A redesign would greatly help.

When I was first diagnosed with COPD I resigned myself to hauling around a heavy tank. My friend had an Inogen that she’d gotten to use when she flew to see her kids. She doesn’t fly anymore so she gave me her Inogen and I just love the freedom it gives me to get around. I especially appreciate it when I go to the casino. 😉

I use the portable oxygen unit whenever walking outside. It is not as noisy as the unit before from a different company. The inogen company so far as been great in providing extra tubes etc. I am happy with the company. Thank You.

I called more than two months ago to find out about one of their products for my mom. During that phone call, I said we weren't interested and please don't call or send anything. I have been getting two to four phone calls every single day for months. I have blocked the numbers over and over again only to have them roll the numbers and keep calling. I had to put a block on all numbers not in my phone book which is really a problem because some need to come through. Have listed about 15 of their numbers with the Do Not Call but still no relief. Hoping this will help.
