Being a senior citizen, I have had many humidifiers in the past. This model SH8830 is the best one I've owned. These features are very useful - fill from the top, remote control, timer up to 12 hours, adjustable mist control, heated mist, room temperature display, and auto shutoff when empty. These additional features, in my opinion, are not useful for me– sleep mode, child lock, and an aroma oil box.
In the high mist mode, it humidifies the room quickly and maintains it well. It is very quiet. I can find no negatives for the unit, although I do want to point out that when received, the gasket in the water tank was loose. I suggest before filling it, remove the water tank and make sure the outside gasket is totally in the groove.
I believe it totally warrants a 5 star review.
