Reality is sometimes there will be an issue even with a great product. I purchased two humidifiers, one worked as expected and the other quit working after a short period of time. Rachel with the customer service team was very professional in handling the issue. If every customer service team was staffed with team members like Rachel, there would be many happy consumers. The defective unit was replaced and now both units are working as expected. The units are attractive and love having the options for the volume of humidity. Thanks for a great product and great support team!
