Very effective ... but some design issues
Well priced and effective, 2 year guarantee if registered online. A few minor design issues: The water reservoir has to be removed and inverted for filling, top filling with the tank in place would be preferable. The multi-colour LED indicator informs users which level of output the machine us delivering ... but why do we need the musical tinkling sounds that occur every time it is changed? If done at night this is loud enough to wake a sleeping partner. It would be good if a silent setting were available. Finally, the base component needs to be periodically cleaned, to do this the hard-wired plug must be removed from the wall and the whole base and wire taken to a sink, a lift-off power- base such as many electric kettles have would make this task so much easier.
These observations notwithstanding, I am delighted with the purchase which has largely resolved the respiratory problems I have been experiencing at night, I awake feeling refreshed, rested and ready to face another testing day of .... retirement!
