Hi, My name is Rob. I remember when I first used Inogen concentrator and I was amazed by how powerful it could be. I came across this machine on a online blog and I was amazed at all the possibilities it could provide for me. I really love this device and I’ve been using it for two years now. I love that it help me, and I love the fact that it is a really powerful. I create this website for people who need information about Inogen. I try post news and changes every weekend!
