I purchased PureSpa™ XL – 3-In-1 Aroma Diffuser two years ago. And a year or so later, the mist output was not working properly. I put it in the closet and forgot about it. While decluttering the closet, I found it again and I thought I should fix it or get a new one. So, I visited the PURE Enrichment homepage and I found out they have a 5-year warranty. So, I reached out to the customer service. I thought they would send me a part, not the whole product. The customer service was quick and easy to follow and I got a new product, which is working well. They have a 5-year warranty. The product is a good size, not too big, not too small. I've never used essential oils with the humidifier, but I'd love to try that, too. It seems easy - all I have to do is just put a few drops into the water tank. I don't use mood lights because I use the humidifier at night and I like peach dark when sleeping. In general, I'm happy with the product.
