It saves lives!!
We would all love to be apart of a great device that saves lives. Imagine watching the news and see multiple lives who were saved because of the Fire Rescue Breather that your investment helped to bring the Fire Rescue Breather to the masses.
I can manufacture and sell my Fire Rescue Breathers using 3D printers , Off the shelf purchased products, and elbow grease. But I would rather build tools for the plastic components and cut manufacturing cost down.
