A side benefit has been keeping a good level of humidity in his room
This is a very small unit.  Do not expect this to work as a home humidifier for anything but a small to medium size room.  I bought it for my 90+ year old Dad's bedroom for the diffuser.  He still has a very difficult time sleeping alone since his wife of 65 years died last year so we thought adding lavender or other soothing essential oils might help.  Do not know if it is coincidence, but it seems to!  We have not had any difficulty with the settings, but we only use it on &#34;run&#34; and not for shorter periods of time - and only on &#34;low mist&#34;.  A side benefit has been keeping a good level of humidity in his room, so we will probably have to find another way to do the aromatherapy in the summer as his home does not have AC.
