I tried this product for free in exchange for my honest opinion. I have  excellent experience with Ultrasonic cool mist humidifier due to convenient top fill by adding water into it or filling top container through the sink. It is really convient to fill up easily without any effort. This humidifier has directional visible mist that provided 180  degree movement . It is also easy to use with essential oil by using special tray for this. It has a great capacity which last up to 36h in run. It is perfect and easy to use, clean up and etc. I would defenetly recommend it.
