I had this CPAP machine nearly six years ago. I used is a handful of times and my wife said either it had to go or she would. It has sat in a cupboard in its box ever since and it needs to find a better home. I was astonished when I looked up to see that i had paid over £700 for it all.
Any reasonable offer will secure it, it's better to be being used than sitting in a cupboard.
The model is a Devilbiss Sleepcube, model number DV54UK-P, it has a humidifier and a ResMed mask.
I have some photographs but I don't seem to be able to upload them.
