"Having an essentially inexhaustible supply of O2 on board changes your thinking.  Flying at 10,000 feet, you don't hesitate to use it.  Cruising above 5,000 feet at night?  You won't give O2 use a second thought."

"I've been using O2 tanks for nearly 40 years.  To contain costs and provide flexibility, I've refilled the bottles myself.  This is always a potentially dangerous exercise.  The thought of having to refill the bottles causes me to restrict or limit the amount of oxygen I use.  Your generator has been a real 'liberator', allowing me to use it in unlimited amounts."
