I was put on the product by the i.t. dept of a very large hospital where i had been deposited for major surgery. they said it was better than the distilled water system i had been using. I resisted as always, but i.t. when i was asleep changed to the oxy; a couple of days later, they asked how i was sleeping? great i said. well you've been on oxy for some time was their response. i haven't changed since as oxy is easy to use and gives me a cool breathing environment which i greatly need to sleep well. i haven't been using the system for very long or i would have given the product the highest rating.
