This is the way to go places. The large battery enables me to stay out longer than if I were using oxygen tanks. I also can charge my battery in the car if needed.

Very good, but medically I have gotten better and do not need to use it currently. My oxygen level is 2. But I am not getting rid of it because I may need it later on. It works wonderfully.

I have had no problems with the unit. I use it full time when I am in Denver. If I didn't have it I could not go there. It is light weight and easy to use. Thank you
