I tried this product for free in exchange for my honest opinion. My favourite feature about this humidifier is that it's top fill. You don't have to lift it to the sink and can simply pour water from the top. This is convenient. It also looks great - slim and tall - very stylish. It diffuses cool mist into the air and it is somewhat quiet.  There is also a separate essential oil tray where I can put a few drops of essential oil on. The only part I think needs improvement is the top lid. It can fall off easily and needs some work to install it back. In general, I would recommend this humidifier.
