Review: Great Product & Great Customer Service!!! - I can't express how much I love this product! I got this for myself for Christmas & use it daily. I love that it's a humidifier & essential oil diffuser, fills from the top (to avoid messy spills), I don't have to keep refilling the water through out the day, (I'm a stay at home mom & homeschool, so our house is very lived in & I diffuse a lot and appreciate the lack of dry air when this is on), the output of mist can be adjusted, it has a soothing light feature for nightime, and works perfectly for my kitchen, dining room & living room! I get compliments that my house smells nice and I love that I can diffuse oils that kill the bacteria in the air and at the same time know that I'm humidifying the air, because I live in a dry climate (especially in winter). I must've unintentionally gotten water in the pipe during a refill (while multitasking), because this product leaked. I was disappointed because my warranty with desertcart had just ended a few days prior to this. I decided to contact Blue Hills via email and let them know my situation. They got back to me almost immediately & let me know they're a family owned business and my satisfaction was very important to them. They gave me a few troubleshooting tips & told me to let it dry for 24 hours & try the diffuser again. They said if I still couldn't get it to work, they would send me a new one for FREE! However, this product wouldn't even diffuse at all after the 24 hours and kept leaking, so I let them know & they said I should receive the new one in 3-5 days. I received a new one THE NEXT DAY!!! That's super impressive to me, especially in these unprecedented times, where it seems like everything is delayed in the mail & customer service tends to lack. I couldn't be any more pleased with this product, or the company & I love knowing I'm helping support a family owned business!!! This product is amazing and would make a perfect gift for anybody!
Review: Top 5 worst products Ive purchased off desertcart! Broke within 24 hours. - Terrible product. I got 24 hours of use out of this unit. Following day I went to refill the tank and the entire gallon of water drained out the bottom vent ports. After removing the tank (view pictures) you can see the bottom of the unit is cracked massively - most likely from the heating element. You can also see in the second picture that the plastic cup area that you use for oil scents was melting. This unit has no longevity and should be pulled from the shelf for insane defectiveness. I will say, it blew out the best plum of steam I have seen yet from a diffuser, and I was in love with the tank size so it can last a full day - but overall this was probably one of the worst items I have purchased off desertcart. Stay clear of this item. Also, the LED light on this unit is garbage. It doesn't diffuse the color throughout the entire tank, just a small LED bulb in the front. Way more negatives than positives. Steer clear! I should have listened to the 1-2 star reviews.

### ⭐⭐⭐⭐⭐ Awesome diffuser
*by S***S on January 3, 2026*

This infuser is a good size. It hold plenty of water to run a good portion of the day on high. The mist can be adjusted from very low to high. And the color changes are very pretty. I think I need to get better quality of incense because I cannot smell it as much as I could like to. But that has nothing to do with the quality of this infuser. I think it also helps with putting moisture in the air. I highly recommend this product. I had an issue with the mist not coming out and all I had to do was lift the tank up and put it back down again. It probably just needed to purge the air out. It is very quiet and it shuts off when the water runs out. Great quality! You will love it!
