I purchased this product when my twins were born, anytime they started sounding sick or stuffy I would fill and turn on the humidifier. They are 2 1/2 now and we now use it every night! I put Sleepy Blend Essential Oils in the tank before bed, and it runs all night long. They really love the lights, and will quickly let me know if I have forgotten to turn it on. We did have a small issue recently with the tank cap, but Juliene with their customer service team helped us out, and had a replacement sent out! Thanks so much for making such a great product, and having a helpful and kind customer service team!
