i like how fast it works and that you can set it to turn off in two hours. If you forget , it automatically turns off in two hours. The scents i chose may not be as strong as I'd like but i can still smell an aroma after its off for hours. Also, i chose this over all others because it can be plugged in. i don't want to mess with a battery or a remote. i have too many remotes in my house. It's easy to move from room, if needed. i really like it so far but it is ugly!

Nice looking diffuser that ALMOST does it well.

Dan September 1, 2024

Easy to use, easy to clean, easy to move. These are well made diffusers and work really well in a smaller space like a bedroom, bathroom,kitchen or office. More than that and they need a second unit to keep up. A typical living room or family room are too much for the amount these put out. I plan to buy one or two more for other spaces in the house.

Super affordable and beautifully designed

TL March 10, 2025

I love this oil diffuser! It makes a great edition to my home office. I LOVE the dark green color and it does an excellant job with diffusing my essential oils to fill the room, and even throughout my house. I've had it for about a month now and have not had any issues.

One Fill Lasts Hours!

Edwin March 20, 2025

I truly enjoy this ultrasonic aroma oil diffuser by Mainstays. I bought a six-pack of essential oils to go with this purchase and my home smells wonderful. So far, there are no issues with this device in the short time I've owned it. You will enjoy the ambiance of a dampened light throughout your day with the convenience of push-buttons to control the unit at your convenience and to suit your preferences. I'd say each full tank of water with essential oil drops runs for about 6 hours in my estimation. If you enjoy fragrances for your space and are tired of breaking the bank constantly buying things that peter out after a week or two and don't last anywhere near as long as they claim on the package, then you can't go wrong with giving this unit a try.

A hard worker!

Sephardi May 17, 2026

This is the grandmother to the other little diffuser from Walmart. Holds a huge amount and it lasts way throughout the day. Makes almost no noise. Jesus loves you and your soul is priceless!

Works, but...

anonymous November 12, 2024

It only diffuses for 2 hours at a time. After that you have to manually turn it back on. There is a setting that makes it run for 2 hours and then shut off, but I do not use that setting, and it does it anyway. Annoying. Other than that, it's perfectly functional. Very pretty too. Distributes the scent of your essential oils very effectively, while it's working anyway.

Cheap

Patricia May 5, 2026

I tried telling myself that perhaps I got a faulty machine. Cheap price doesn't mean anything. I had this a month before it stopped working. The light turned on and that was it. I've did everything to try and make it work again, including cleaning it, not overfilling it and making sure it was in a level surface. For the time that it did work, it worked great. But that was very short lived. Walmart wouldn't let me return it so unfortunately it's going in the garbage. You will find better ones on Amazon than at Walmart. My mistake and it won't be happening again.

I would love to exchange the aromatherapy device I bought on pick up today. It does not work. I'm frustrate. In order for return the item for another aromatherapy's. I'm very disappointed and discouraged at the price and quality service and merchandise has gone up. It'd be nice to honor the exam Mmmmmmmmmm

STOPS WORKING FAST DON'T BUY

Sol January 26, 2025

So after using this diffuser for five months, it stopped working. The only thing that works are the lights other than that it doesn't defuse anything I cleaned it and everything and it doesn't work. I am very disappointed because now I have to buy another diffuser.

WOULDN'T RECOMMEND !!!

Stephen January 22, 2025

We needed a smaller one for the bedroom and we bought 1 brought it home it didn't work no matter what we did, so we exchanged for a second one well it worked for about 3 mins and then started rotating thru light settings and never started misting I'm guessing it's because it was being sent thru every misting setting just like the lights were! So out of 2 we NEVER got one that worked! I wouldn't recommend to anyone!
