I haven't re tried it yet without the humidifier but without a heated hose it is useless as I live in fairly cold climates and the mask doesn't seal properly if too cold.
When I tried to return the battery they refused and were not at all helpful. If I would have known that it wouldn't last a whole night - I would have invested in other power forms for our camping. I just thought that where we usually camp there is access to power to re charge during the day so the battery could be ok. They should be more specific about those things on their advertising and training for those selling them!!!!!
So now I am stuck with a battery that I have to charge up frequently that I don't use!! what a waste of money. I should have asked here before I purchased it - or am I missing something? Do I not know how to use it?
It's been a few months now so too late to fight it - but my husband was diagnosed with cancer at the same time and I didn't have the energy to fight it... now I am getting a bit mad again about it all.
