GUILLE T.
Would give 4.5 stars.
Would give 4.5 stars. Positives: Excellent Customer Service. Very Reliable. Quality, compact construction. Easy to change columns, clean filter. Fairly Quiet, though still a little 'loud' late at night, but not annoying. Negatives: Wish they had used a 'Tactile' On/Off Switch. Difficult to turn on in the dark ( can't find the switch ). We don't leave it on 24 hrs/day because patient does not require OX all of the time.
