First off, I really love that this humidifier warns you not to put any essential oils in the tank, because doing so could crack the tank plastic.....guess who did that with the last humidifier she had?! -I did!
So, the optional essential oil/VAPOR Wick tray is a great new feature. I also really like that the shape of the tank, it allows it to dry out much easier in between uses. One tank of water lasts the whole day. IF* it had an internal night light I would give it ten stars!
I was given this product for free in exchange for my honest review.
