The mist maker slowly declined in functionality for about 1 month after buying it. I tried removing the discs and cleaning off all of the deposits yet it still outputs minimal amounts of fog compared to when I first received it. I would not recommend this item to anyone who wants a fogger that is going to last more than a month. It crapped out 2 days after the return window closed. Cheap POS. *DO NOT BUY UNLESS YOU ONLY NEED IT TO WORK FOR A LITTLE MORE THAN 30 DAYS*** ps if you need one that actually works for longer check out hydronic specific foggers
