Battery is good addition to portable concentrator
This battery is able to adequately extend the usable time of the concentrator so as to provide about 5 hours of use. In most cases it will allow extended time in case of emergency and/or time until a regular oxygen supply is available. Recharging is easy and fairly quickly.

Fascinating study in human relationships
Fascinating story of a man who is skilled and meticulous in medicine and human nature. Interesting and funny characters make up the community. Personal relationships ebb and flow throughout. Fun to watch the whole series many times with new pieces appearing with each viewing.
