Uses a few drops for fragrance and aromatherapy.

Simple setup with minimal effort required.

Features multiple brightness settings for customization.

Can be conveniently versatile, but also too short.

Offers affordability, but can be perceived as cheaply made.

This is my second time purchasing this oil diffuser. I bought some pricey glass diffusers for around $150/each and this $15 one is the only one that still works! The design is a bit campy / cheap looking and the water capacity could be larger but it works which I cannot say of the others I got!

Still Works While 10x More Expensive Ones Broke!

Gor it's small size it can fill a room with the clean smell of your choosing. Would be a great choice as a gift for the person who loves scents in the house.

This is a pretty simple Diffuser, looks like a vase even has an optional light you can turn on or not when diffusing
you simply add essential oil and water to the fill like then plug in lasts a few hours with the fragrance 
includes a USB cord and even has the adapter for wall use! 
The design is simple and attractive - easy to fill and use. 
After I used this once I found myself thinking they should really make one of these as a humidifier with a dome for an individual plant!

Mainstays cool mist ultrasonic aroma diffuser

This Mainstays 100mL Ultrasonic Aroma Oil Diffuser is a great little diffuser. Especially for an office area or small room. It is very simple to use. Just plug it in, fill it with water, and turn it on. It releases a cool mist that, with the help of essential oils, smells really amazing. I like to use mine daily while I work at my desk. I choose a different oil depending on my mood. I like the fact that it is on the small side because it makes it easier to move it and also keep it clean.

Small and powerful

I love this oil diffuser. It is so easy to assemble. It's compact and illuminates while in use. You have to put water in the base and a little bit of scented oil. Once you do that you can plug it in and turn it on. But I highly recommend this product. Also I suggest you use this oil diffuser in a small space.

Great for a small room

dislike was when where I put it was off balance, and it didn't work. It's actually a great feature but I was stupid thinking it wasn't working. The light didn't bother me but I do sleep with my tv on. If you are the type that has to have complete darkness I would suggest using when awake. I didn't hear it because it was so quiet. I muted my tv a few times during phone calls and such and not one time did I hear it. I do wish it held more water, but it isn't a huge bother. My lizard loves it too since it is close to his cage. It would be perfect for a small child nightlight with kids who need it for medical reasons. Mine is in my bedroom and I love the fact I don't notice it.

small with many things it can be used for

I do love this item only downfalls is the lid just sits on the base.... so if it gets knocked down, the lid will pop right off

This item broke after one month's use. Additionally, it only has one button that controls both the diffuser setting and light setting.  It is very hard to set to the two settings desired. The double click to swap to light settings is finicky.

Broke with a month

Doesn't work well at all, put too much oil into a diffuser won't work only wanted to put more because it didn't smell strong to begin with not worth the buy. I wanna return it but too lazy to return it to Walmart… just being honest.

everything came in as it showed. But, it only lasted less then a month. first it worked perfectly, then a month later it just turns off and stopped working.

Don't buy this item!

Ease of use

Customers praise the product's ease of use, compact size, and attractive appearance, which complements home decor. While some appreciate the simplicity of the buttons, others find them finicky or hard to press. The cord's USB and wall adapter options are convenient, but some find it too short. The water capacity is sufficient for some, but others wish for a larger reservoir. Overall, the product is accessible and easy to use, despite some minor drawbacks.

Compact and attractive product with convenient features and minor drawbacks
