Review on AmusedNd Portable USB Cool Mist Humidifier: 300ML Mini Bedroom Humidifier with LED Light, Ideal for Kids, Offices, Bedrooms, Dorms by Dustin Schultz

Because of how they work, cool mist humidifiers typically require less power than warm mist machines, making them more efficient and lowering your energy bills. I had a bigger one but it was too big so I searched Revain and lo and behold I found the perfect size for my nephew who has asthma. I put it on the nightstand by his bed and it comes out with just the right amount of smoke for the rest of the morning. Thanks again Revain for another great product.
