TOO EXPENSIVE! Even the accessories are very high in price. Goes through batteries (even the expensive double ones) too quick. If you are going to spend the day somewhere, you have to take several batteries with you. Then you need the back/waist pack to carry the extra batteries, and discover that is too expensive to afford.

Parts that recharge batteries, they wanted $150. Found at Walmart same thing for $50.00.

Since I bought the Inogen 4, I have had the concentrator replaced twice due to system errors. I have had the battery replaced twice. All of this in less than one year. Am somewhat disappointed to say the least, that an item that cost almost $3,000 has had so many problems. Inogen has been good about replacing the bad items, but the quality of their product has me concerned. I am concerned about future failures with the Inogen or the batteries. The concentrator is life time quarantee, however, the batteries are not and are quite expensive. Shop around before making your decison to buy an Inogen.

Forced to reset approx. every 8 to 10 days due to no airflow. Usually happens while sleeping & I don't notice red light. Able to reset in morning. Have several friends with Phillips unit prescribed by their Pulmonologists. It is much quieter, lighter & am told it is problem free. Supplied at no cost, same as Inogen.

I got rather frustrated with the salesman i spoke with. I specifically asked him how long a double battery would last. The answer I got was 4 hours, no conditions or stipulations. So I ordered the Inogen with a spare battery. Before using it for the first time I made sure both batteries were fully charged. The day I used it for the first time was what our local forcaster's call a "poor air quality day", so I needed the setting to be one higher. It's a good thing I took the spare battery with me. The first battery ran down in less than 2 1/2 hours. I managed to get home before the second battery died. I now take at least 2 batteries with me every time I leave the house.

Love my Inogen 4 Unit. However the larger batteries do not weather well. That is they frequently disfunction before even out of warreantee. I now have a third that just suddenly shuts down and then displays a system erro messahge. Do the wait a minuste and then reattach but it happens again . Thats when I call for a replacement. This one is 2 months old! Keep asking if it is my untit. Keep being told it is the batterie.

size and weight

Too costly for the average retiree. Needs info on when replacement parts are due (filter cartridge). Need info on where and cost of replacement hoses and nose pieces. Additional couplings to make different length of supply hose for traveling and different rooms in the house.
