Free once again
I've been trying for sometime to get my own personal portable concentrator and not having much luck. I thought this was my only way to go because my oxygen bottles would run dry after like 20 minutes. Than I find out all I need really is a different style regulator and it's pulse but no batteries to worry about so no adaptors or plugs to worry about. Thank You Adapt for helping me become independent once again.
