I Love This Diffuser! I have had my first one about 6 months and it has not skipped a beat! It is a great product for the price and the size is perfect. The changing lights are cool and pretty. I gave them as gifts,and everyone loves them! Just bought more for every room in the house. I would highly recommend this diffuser to anyone.

Ex Output:
positive
