Product review (5 stars): Highly recommended!
Love this little device.  Wish I would have bought two of them so I would have another one for different area of the house.  I live in a very dry climate which causes a lot of dry skin so I purchased a humidifier but then had no way of knowing how much moisture was appropriate.  This device took care of my concerns.  It lets you know whats a comfortable amount of moisture and heat.  Even gives you a happy face when you're in the comfort zone!
