The humidifier works great, it has a large tank andyou can set it for the humidity level from 30-90% in 5% increments. The mist level has 3 different settings. I have only a couple issues, don't buy it thinking that because it says "Smart Humidifier" on the humidifer, that it has an app or wifi/bluetooth, it doesn't. The "Smart Humidifier" refers it having an Auto Mode and a Humidistat. The other issues is one that probably happens with most humidifier with a built-in humidistat, the humidity level reading on the humidifier is generally higher by 7-11% from a stand alone humidistat, which isn't a big issue. You just have to set the level on the humidifier to a higher percent, like to get a 35-40% on the stand alone you have to set the humidifier on 50 or 55%. It's a really good humidifier and it's easy to clean, worth the money.
