The sales person,Diana, was very knowledgeable and helpful. I chose the Rov 4 because it was the lightest portable and would allow me more freedom to engage in various activities.

I love that I can take my portable inogen anywhere, but I disagree with their repair practices. It takes them up to 5 business days to speak with a return specialist and once you send it in for repair, it can two weeks! That's a total almost 30 days to get my machine repaired and sent back.

Good oxygen flow, but the in-home box is way to noisy.

The only thing I got against Inogen is that you have recharge the battery in the unit. There should be a better way

They main complaint I have noticed is battery life is only 2-3 hours not plugged in and unit is a lot heavier than I expected referring to their advertisement. The carrying case supplied is very loose fitting around machine and the cutout for the charging port is too high above the port. Also wish unit and replacement batteries were cheaper. Otherwise the unit functions as described. Better than carrying around oxygen tanks.

The machine worked fine for a few weeks/ a couple months. It is a rental thru my insurance co. Then it began to alarm regularly. Changed the cannula, no difference. Fully charged. I live a mile high. Winter temperatures low 20℉ ~ mid 30℉s. It will turn on, then stop with no alarm, is fully charged. So it is getting returned to rental place. I have oxygen tanks so I am not going to hospitalized due to no O2. I will ask my pulmonary doctor to write me a prescription. I will purchase a new unit. The rental place said the home unit not working was “My Fault”. I am also returning the loud home unit. I have already purchased a replacement. The estimated date failures was about March of 2025, almost every day alarms, malfunctions.
