Bests & Worsts Reviews from Amazon

I'll start of with it IS VERY quiet. You DO get a slight boiling sound on "warm mist", but it's not bothersome. That being said, lets move on. Received it at 7pm, had it running by 7:30pm. BY 6 AM the water level was low. It would probably have lasted until 7:30 or 8am, giving it around 12 hours (cool mist) run time on high before needing a refill. Now it was on high all night (cool mist), which brings me to my only REAL complaint. You can't preset the level for "automatic". It's either 60% or nothing. Has a big beautiful number on the front to display the humidity in close proximity, but you can't set it to a specific level to turn off at. It LOOKS like you can use your phone with an app to set it, but NO. About the only thing the app does if this is all you have is collect a bunch of info IT DOESN'T NEED to do the job. It will show you the humidity level on your phone, but if you're anywhere in the room the display is quite large and easily to read, making the app nothing more than another way to get spam. (oh that tasty spam) IF you could PRESET the output % for "automatic", this would be a solid 5 star, as it puts out a nice stream of mist, and is VERY quiet. And honestly, it would probably only add a few pennies to the cost to do this... OPERATION: 3 mist levels and 3 heat levels can be set. Putting it in "night" mode >appears< to turn off the warm mist (removing the boiling sound), along with the display. Even on low mist level it puts out a fair amount, and high you almost have a fog machine, making it great for larger areas like the living room. It has an "auto" setting, but as stated before it will only maintain the humidity at 60% Overall, it works quite well, and is quiet enough that you'll barely notice it running even in a very quiet room (even on warm mist). Good value, but would be a PERFECT value if you could set the level!!
