This machine complete with accessories including humidifier to prevent drying out, face mask, breathing tube carrying case which fit all components easily, and instruction booklets. 

Used only about six weeks about three years ago and all in excellent condition.

It is still the most popular model of this highly successful Australian company.

It was bought for an apnea problem, but because of personal unusual physical nasal and aural layouts of my internal head passages, use of it was discontinued on the advice of my ear specialist.

The complete kit at the time cost well over $2000
