I have been using the humidifier for about two weeks now, and I am happy with my purchase. It is quiet, easy to fill, and user friendly. The only thing I wish was different was that the light feature did not come on automatically with the power button. I have the humidifier in my baby's room and would rather have the option to turn the light on rather than to turn the light off (the light wakes her). Additionally, when you turn the light off by selecting "sleep" mode, the whole system turns off and you have to wait a few second and then press the timer button to "wake" it back up. Other than that, I am very happy with this product and would purchase it again.
