The changing colors are fun! The mist output is light but enough to spread the aroma in a small room. (Posted on 6/26/2018)

This will be the third time I've purchased this diffuser. I LOVE, LOVE, LOVE the features and output is perfect for my use! HOWEVER, I purchased my first one in MAY 2016 and it died in short order. Trying to get replacements for product failure is BEYOND frustrating! So I went to Wal-mart for a diffuse.The wally world knock off was slightly less expensive and no hassle but it failed. I purchased the SECOND one was purchased in SEP 2017 and it died last night after only EIGHT months of proper use and cleaning per instructions. I'm in the middle of moving several thousand miles away and have paid UPS 2nd day AIR to receive in time before I move. So I have a diffuser for the car and hotel rooms along the way. I suggest if you love the AromaTools product, plan on buying one every year! God speed this pkg on wings of eagles and make sure they work because I can NOT live, sleep or function without my diffusing my doTerra Oils and i will NOT go big pharma! (Posted on 5/18/2018)

I am pleased with the operation of the Diffuser. However, I am unable to open it myself. It requires my husband's brute strength to do so. I am hoping repeated use will eventually allow me to open it myself. (Posted on 5/7/2018)

I have ordered quite a few of these diffuser's, they work great when they work, I have had a few come back, customers say the diffuser goes on then in a couple of minutes off, have replaced them...The company is good about getting a replacement out. (Posted on 4/9/2018)

I received my diffuser and set it up immediately and it worked great...the first time. I actually own a more expensive diffuser so This was for my desk at work. Overall I'd have to give this an 8 because it seems to have a few quirks. It shuts off on a whim, sometimes beeping first & sometimes not at all. I've considered returning it for this reason - but then again, when it works it's great. And the oils I'm diffusing make me so mellow that I'm not inclined to want to get in anyone's face (lol) :) .

First time diffuser purchase, received on 08/17/2017, started using it not a problem. Then on 08/25/2017, four days from receipt, I set for 30 minute diffusing and it only ran six minutes. I waited, tried again, ran for 8 minutes. Tried this morning 08/26/2017 and it only ran 10 minutes. Bummer that it crapped out on me so soon. Now have to go through problem of returning it. Not happy with this product.

I personally have had this diffuser for over a year and I love it so much that I purchased this one for my daughter-in-law. I love the timing feature and the ease of filling it up.
