I have had two, was super easy to take the cup off and mount in a screen cage by making a small hole,
BOTH units had issues, One moisture builds up inside the cover, causes all sort of problems.. Bascically the timer both frequency or duration fail to work over time, now using mine on a regular plug timer..
Pump is small, simple run dry the spring will overheat and break.. As timer starts to fail, very likely..
Customer service is supposed to be ok, lots of people have had replacement units etc.. however repeat problems..
Sadly may be me but two units died, for cost using my own timer as I am now I could have purchased say a mist king..
I look into aqua zamp, or Mistking.. sadly the monsoon seems to really be overpriced and not all long term reliable..
