I bought this for my daughter's room a while back as a birthday gift. She just had to have it. We both are kind of Hello Kitty freaks, so I was excited to buy it for her and honestly, I wished I could have it for myself! This humidifier is small and works generally well for its size. She needs it for the winter months mostly, because it gets really dry and she has gotten nose bleeds. I have noticed that after purchasing the humidifier for her, she got less nose bleeds. She sleeps better as well. This product is very quiet and it was not really expensive, in my opinion. It was a little more than some humidifiers because it was Hello Kitty, but overall, I think the cost was good. I would purchase this one again if the first one stopped working. And I definitely would recommend for anyone with a little girl. It is a fun little humidifier that works really well that any little girl would love to have! Output Volume The humidifier is small, so it is only good for a small room, like a child's bedroom.
