I own both an Inogen 2 and Inogen 3. They both have worked well and each has its good and not-so-good points: The Inogen 2 is slightly lighter than and oxygen tank (size C), but is more ergonomic in that you can adjust the shoulder strap so that the Inogen 2 sits in the small of your back. It does, however, pull on your shoulder. With its large battery set on 2, it will last 6 to 8 hours. The newer Inogen 3 is MUCH lighter and easier to carry, but with its larger battery it only lasts 3 to 4 hours. You can overcome this problem by plugging it in to your car every time you're out running errands. It has lasted for a total of about five hours through a movie, lunch, and grocery shopping with charges in the car between stops. I have never had a problem with the Inogen company, purchasing and maintaining the Inogen 2 or purchasing the Inogen 3. When it was time to replace the oxygen cylinders in the Inogen 2, I received a notice on the machine window. I called and ordered the replacements which came very quickly and I replaced them easily with the (pictures) instructions. I'm sure I will be a customer for life.

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.

The InogenOne 64 unit has worked very well. With the large battery it lasts 3.5 to 4 hours at a 2 setting. The reduced weight is definitely a plus and adds to the comfort of portable carry. The car charger works well and is another plus.Overall I'm very happy with its performance. My first comment as to improvement would be the placement of the cannula nozzle fitting. It points up, which causes the cannula hose to bend and kink. If it were horizontal or down it would be better. Another solution would be to have a U-shaped connector (with a swivel joint would also be useful). I was unable to find such a connector on the market. My solution meanwhile was to place 2 small snap rings on the other side of the machine and let the cannula hose loop over the machine and through the 2 rings, which gave a wide curve and kept the hose in place without kinking (I attached the the 2 snap rings to the case with auto trim adhesive strips cut to size) I also found the backpack to be too large for normal use. I would like a smaller back pack for just the machine and maybe a charger and an oximeter

The unit is so portable and easy to use.

At first the website was a bit confusing. I could not find the price until I searched it in Google, then it came up on the website. Getting accessories was a little better but I had to search for my particular model a couple of times before I could order what I needed. I love my machine, just wish items were easier to search on the site.

A very useful O2 producer and portable. I use it out of the home, while driving (car charger plugged in), and occasionally while shopping. I live in a Senior facility where I have Dinner and often meetings or entertainment in the common areas. Using a walker to carry the Inogen and spare battery, I can get enough running time for long meetings and dinner and a movie.

Even though I had to pay for my Inogen 1 G4 myself, it has been worth every penny. Just as the ads state, it has given me a freedom that I never could have gotten from having to lug tanks around. It is light weight and dependable. I bought the hip pack for my Inogen unit, and that has been the best accessory. My Inogen now sits comfortably on the small of my back, and I have both hands hands free. No shoulder strap digging into my neck or slipping off my shoulder. I can walk fast and breathe easy. Perfect!
