Small and powerful

MD20 January 19, 2023

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.

The diffuser presents a classy appearance.

Rich December 19, 2022

The MainStays Cool Mist Ultrasonic Aroma Diffuser is well constructed of quality materials. Assembly and disassembly is straightforward, easy and quick. The power supply is included with the diffuser, you can choose straight USB or USB by way of the included transformer. The diffuser presents a classy appearance to my room while adding a favorite aroma throughout the home. I recommend the MainStays Cool Mist Ultrasonic Aroma Diffuser.

Lighted Diffuser

Homebody December 25, 2022

Truly lightweight and quiet, this diffuser is easy to use and runs for a decent amount of time with each filling. When filled with RO water it ran for about 1 hour. With Berkey water it ran for a couple. Be aware that it is lighted, so if you are using it in the bedroom, that will be a disadvantage to those who prefer to sleep dark. The unit is low-profile at about 5 1/2 inches tall & 4 1/2 inches wide. The cord (about 3 feet long) can plug in to an outlet or to a USB port, which is very convenient. I’m pleased with this diffuser and glad to have it freshening our home.

Great Aromatherapy

JJ December 26, 2022

I have to note that the essential oils are not included, with that being said this diffuser is truly a smallwonder. It has my whole apartment smelling absolutely radiant. This is one of the best things that I have ever owned. Be sure not to overfill the water over the max, it has an indicator on the inside. The diffuser does wonders for my nose, and I am not as congested as I usually am. I breathe fragrant clean air, and it barely makes noise. Everyone in my household has congestion/ sinuses, and this has vastly improved the quality our breathing. This diffuser is so aesthetically pleasing and adorable, yet powerful.

Great little diffuser

Ozarkcrafter December 24, 2022

It's not to big and fits perfectly in a corner of my little kitchen. I like the color as well and the amount of mist it puts out is just right. I believe it will give us a lot of use.

Great diffuser for the price

BigManEarl January 11, 2023

Great diffuser for the price. Quality seems on point, so far so good. Only complaint I had is it not including some oil as it would've completed the kit. Overall I would recommend for the price.

Colorful Aroma Diffuser, Lights Up

Sunshine December 20, 2022

Here are the positives: This Mainstay aroma diffuser is a pleasing teal blue which is beautiful when light is on. I noticed that this diffuser compared to other Mainstay diffusers has a reservoir which holds twice the amount (100 ml) compared to most that only hold 50ml of water. This makes a big difference on how often you need to refill the reservoir. For me it seemed to average once daily. Another plus is that the 2 piece power cord detaches at the unit so you can easily transport to a sink for refill. The unit does automatically turn off when the unit is empty. Now the negatives: I was surprised that this unit did not include at least 1 sample bottle of diffuser oil like most others seem to include. The instruction sheet recommends 3 drops of oil but I found I needed to add double or triple that amount to notice the scent in the room. Other wise you can only notice it if you are directly above the diffuser. I found the on/off button to be finicky. Instructions advise to hold button 3 seconds. When I did this the unit failed to come on and I first thought it was defective. Two quick push of the button turned the infuser and light on for me. It was hit and miss to get the light to turn off and leave the infuser on or get the unit to cycle on the 30 second intermittent intervals. I have not had the unit long so cannot speak to durability but overall I felt it had more positives than negatives.

Compact Diffuser

TiredButHappyTigerMom December 21, 2022

A very simple and compact diffuser. It comes in a variety of colors to match any decor. It's quiet and easy to use. Pour in a diluted mixture of water and your choice of essential oil, and turn it on. The lid is a little hard to take off because the lid is big and slippery. I wouldn't recommend this product for people who have arthritis because of the lid.
