Inogen Model G3
The unit is easy to operate and fairly quite but don't care much for the pulse system,does not put out enough for me. Even on high I still have to use extra oxygen to get what I need. My employer has the G5 but I am not sure because of the pulse system. The battery does not last long enough on high so when I go visit family I always make sure I have extra bottles of oxygen to get me by. When my oxygen gets low I have to set for a time to let it catch up. I don't walk fast either or very far.
