Looks like there aren't enough negative mentions yet.
The output is really strong at the highest level and it did last about 8-9 hours on high as well. It's very quiet even with occasional gurgles, but the nightlight is a bit much for me. I found a way to cover it mostly but it's still brighter than I personally would like. Overall I can handle the light as long as it does it's job and I don't have to worry about mold. I'll be using this regularly.
I would recommend this to a friend
It does take a longtime to start the first time the only issue i have so far it does not last 14 hr as promised so far it has lasted 8 hr with one tank, what is disappointing the blue night light is nice not to bright, and the machine is very very quiet
No, I would not recommend this to a friend
