It tries hard.

This little concentrator does the job as far as it can. The main problems are the battery life is too short and there is nothing to show when it is done charging. It is very quiet, even on full speed. I already knew it would not put out the amount of oxygen my doctor wants me to have so that is not considered in my rating. It does a good job of giving me a boost when needed.
