## Customer Reviews

### ⭐ Just Stopped Working
*by S***E on November 27, 2013*

I don't know what happened to this diffuser but it worked just fine the one time I used it. When I refilled it the same way I did the first time, the little red light was faded, blinks, but just won't turn on. I liked this color and size so much. In addition, it's very hard to open the top and open the inside top to refill it. The top is suppose to open when you turn it counter-clockwise slightly but it fits so snugly that it takes time to get the top to loosen enough to open. The inside top opens from the outside rim and not in the middle.I sent feedback to the seller but have not heard anything back. I even went to Mammoth's website but there were no troubleshooting instructions, actually no instructions at all, except what's on the box. I'm so disappointed. I bought another one but had to get it in a dark fake wood-like color instead.

### ⭐⭐⭐⭐ great!!
*by T***A on October 27, 2014*

First of all, let me say that I love this diffuser. The look is very nice and it has a low "white nose" hum when it is on. I gave it four stars because it is very temperamental and all parts have to be exactly in place for it to work properly. Even though I watched the video,I still had an issue with it and I thought it was broken. The only other issue is that it has these lights that don't go off. Since it is black, I just put a few pieces of electrical tape over them. It's perfect now!

### ⭐⭐⭐⭐⭐ Great little diffuser!
*by C***W on January 31, 2015*

This is a great little diffuser! It operates like all the ultrasonic diffusers and puts out enough mist to fill a small room with scent. I have had it running almost continuously for the last two days and it has had no problems. One reviewer stated that there was a design flaw because the unit will stop running because of a low water level when it actually still has water in it. This is true, but I like this feature because it allows me to use citrus oils in it because they won't touch the vibration plate (oil floats on water). The directions are clear on how the buttons operate, so I'm not sure why some people can't figure it out. I set the unit on the 2min on/2min off setting and it was still running when I woke up. I have the glossy black unit and it was a little difficult opening the unit the first couple times, but it is not a problem anymore. The lights do not bother me, but the two small leds on the outside of the unit are a little bright. Overall I am happy with this purchase, it works and it was very affordable.
