        Convenience away from home & peace of mind

        Works great for the 3.5 hours. Wish the Oxygen Concentrator came with instructions or a booklet explaining how to use it. Trial and error. Didn't receive the purchased additional filter, so can't give it 5 stars.

        What a wonderful thing.

        This wonderful little machine has restored my mobility and freedom. I ordered an extra rechargeable battery for backup. It all fits in my small backpack and is easy to carry. I can now go to the grocery store without concern.
