    It has been a full month for me and my G - 4 , it has made my 16 stairs a lot lighter I also just bought the Oxy - View Glasses so as not to have the tubing across my face. I also want to say Thank You to Eric my sales rep he was great to work with.

    Excellent Oxygen Equipment
    I absolutely love my Inogen G4 concentrator in every way possible. I will be buying the Inogen GS-100 for home use very soon. Great on-line company to work with also....

    Equipment and customer service review
    Great machine. I've had my G4 for a few days over one year. It travels with me on the plane, in my car and runs non stop while I sleep. It gets a lot of use. Two days ago it started to make a knock/vibration when on level 1 or 2. I called the customer hot line yesterday, mid PM, a lovely lady named Emily, listened to my problem, listened to the machine sound and assured me a replacement G4 would be sent to my home. Today UPS was at my door, early AM with a replacement, waited for my machine to be packed for return, to complete the transaction. WOW!! Did not expect over night. Great service. Thank You.

    I have been using this unit for 4 months now. I has not skipped a beat.... I bought the bigger battery but I have never even go close to using all of it.. I put it on charge when in my truck.. and on charge when home or in the office... I have gone 5 hours on a setting of 2 and still had 25% left.. I find it amazing how this little unit can do what it does and be so quiet at the same time.

    Runs hot and 3L Pulse
    This unit is great if you need 2L on pulse while mobile; easy to carry and quiet. Very warm as the exhaust is vented on both great in the winter, not so great around the house/office. Buying a lighter unit is great unless your situation gets worse, then you have to upgrade and upgrade again.
