    Carry case 1 people found this helpful

    The unit is fabulous, the carry case is not. I was hoping they would design a new one with 2 handles.

    Fantastic equipment and wonderful service 0 people found this helpful

    I was extremely pleased with Jake's knowledgeable, helpful and friendly service with the purchase of the Inogen G4 for my Mom. She was newly diagnosed with a need for oxygen, and I must say, the portable convenience and light weight of the G4 is perfect for her. Jake made sure we received everything in a timely manner, and made the process of purchasing this equipment easy. I definitely recommend The Oxygen Concentrator Store, and enjoyed working with Jake. With the Inogen G4, there is no need for cumbersome oxygen tanks. Truly, it is the only way to utilize oxygen!

    Quick 3 day delivery as promised. 1 people found this helpful

    I received the G4 unit about 2 weeks ago. It arrived in 3 days as promised. I am very happy to be rid of bottles and already have service coming to pick them up. Keeping the rented large compactor for bedroom, but may buy a larger Inogen for that later. I am not worried about power outages because we have two excellent generators or can recharge the little G4 from cars also in that event. For me, it is working well on setting 2 and is all as advertised so far. Only time will tell if it continues to be reliable, but right now I love it.

    Great product 11 people found this helpful

    I checked out another small concentrator from a different company. Twice the weight. This unit is small and works fine. Very happy with this unit.

    Noisy and tubing smells 12 people found this helpful

    The G-4 makes a noise that sounds exactly like popcorn popping. I was told by the customer service people that all G-4s make this sound. The tubing has a strong acrid odor which is unpleasant and smells very unhealthy and suspicious. There was no explanation offered for this problem.
