Perfect!
I thought I was going to have to give up my Inogen. It was not only out of warranty, they stopped making this model. It would make loud alert noises when I tried to use it. So I went looking and found the parts and changed them out myself. Blessed relief. I have my O2 machine back. It was exactly what I needed and what I ordered. I always think thee kinds of things are expensive but it’s like $100 for the parts or at least $1500 for a new machine. Score. I am so happy. Shipping was quick, too
