Mainstays Cool Mist Ultrasonic Cut Diffuser- Black, 100ml, Use with your Preferred Scented Oil

This diffuser is very small, with about 1/2 cup capacity which I normally would not like. However, it fits perfectly where I wanted it and puts out a good stream of scent.

This is a nice little diffuser. It uses a gentle, no heat, smoke-free mist to distribute aroma in your home. It's safe to leave unattended because if it runs out of water, it auto shuts off. It glows with color changing LED lighting. I've tried it so far with apples and cinnamon fragrance oil and with citrus oil. I love them both. I use the setting that it puts out a mist every thirty seconds or you can use the constant mist. So far, less is perfect for the room I use it in. If this model lasts some time, I plan on purchasing more for holiday gifts. I would definitely recommend this diffuser for others to try.

For $15, you really can't beat this. It's easy to use and clean. The mister and lights all work great. I found it better than a previous ,more expensive type, that I had, which broke after 6 months and was always making a mess. This one us is a good choice.

I like the style of this diffuser. I wish it was bigger. Also, I couldn't find a mark for the fill line, so I had to keep trying it until it finally worked.

The size is misleading, bu size im speaking of the actual water and oil container compartment. It does run a few hours if you choose the lowest timing setting, but its really only good for a very small space . Very small area, like a small bathroom.

This product has pretty lights but doesn't put out hardly and scent even with my excellent grade oils. It costs a lot for a night light. I got a cheap little diffuser with a fan the same day and that one works great!

I purchased mine from local Walmart and it worked for one day making my house smell amazing! During the night it got loud and starting to make weird noises. Now it doesn’t blow any air or smells out. Water level doesn’t move. All lights come on but nothing. I’m not pleased with it, which I really wanted it because it’s so cute and small and the price was amazing!

Worked great for the first few uses - great for a small room, as it's a very small tank which is fine with me. But after the first few uses the top is harder to get off each time… I've been using a knife to try and pry it open and it won't budge. Not sure if it's the oil inside it or what, but sadly cannot use anymore.

While I ordered this item in 12/2025, I did not use it until mid 02/2026. By mid 03/2026 it was not working. While I loved the lighting %26 when it briefly worked. I am extremely disappointed that it only lasted an approx. month.

This is thing is junk. I've had several oil diffusers and nevwr had any issues with a single one of them till now. It doesnt diffuse aroma into the air. now it won't open! I'm trying to pry it open with a knife and gave up. It comes with a cord but no box to plug it into, wire is short too. Absolute terrible product.
