Dehumidifier is good enough but the app has some issues as others have noted before. The notification for the tank being full can only be seen when the app is opened, which is really inconvenient as I have to open the app multiple times a day. So the wifi capacity is basically for remotely turning the machine on or off. Ionizer can only be turned on through the app and when you turn the machine is turned off, the ionizer setting in the app is also turned off.
