quite happy with this a great find [SEP] i had some reservations i ve seen the round wood ones around but never made the leap i was afraid the ceramic would make this too heavy and bulky but it does not it s quite lightweight and because it s vertical saves some space it comes with extensive directions a nice change but is really very easy to use and set up it s very hot and humid where i live so i was also worried that adding more humidity to the air would be a bad thing however the air that comes out is quite cool which seems to cool down the area around it and by it i mean me i found it very comfortablei wasn t sure how i felt about the colored lights option but i love it you can choose red or a brighter red and also green and a soft lavender blue with their corresponding brighter shades you can choose to have your color or opt to have the unit cycle through them all it s quite restful you can of course just use the white light you can set the steam for a continuous output or intermittentthe until must be cleaned after hours of use it doesn t hold a great deal of water so i was wondering if that was going to be inconvenient i ran it for two continuous hours and i could tell that filling the tank twice would be about hours so that s easy to keep track ofall in all i couldn t be happier with this unit it checks all the boxes and i can enjoy my essential oils in an peaceful comforting environment highly recommended
