URPOWER300ml Aromatherapy Essential Oil Diffuser Ultrasonic Air Humidifier AUTO Shut Off Scent Diffuser Night Light 7 Color Changing LED Lights and 4 Timer Settings for Bedroom Office Home

My wife loves it

This is a great room diffuser. It’s easy to operate and I like the “turn-off” safety feature. Very attractive and works great!

Works well, but it’s kind of finicky

I purchased this URPOWER Essential Oil Diffuser along with another of the same brand, but a smaller size and capacity. This diffuser will take up to 300 milliliters of essential oil and water mix. The unit has 4 settings for operation. 60 minutes,180 minutes, 360 minutes and ON. So, you can set the unit to work whichever amount of time best suits your needs, or if you prefer, you can set it to ON and it will run until there is no more solution left, When it will turn off automatically. The unit also uses four bright LED's that give the whole case a soft glow in various colors. There are two separate control buttons. One controls the time and the other controls the light. By default the diffuser will start at 60 minutes and cycle through all the LED colors. I have discovered that some colors seem to work better with different essential oils or moods. When the color cycles around to what you want, push the "Light" button again, and it will remain that color of light.The diffuser is very quiet while it is running. All you hear is a soft hum, and occasionally it will gurgle just a little. (I don't know why) Which essential oils you use and whether you blend them or not is up to you. Each oil generates its own feelings in you according that oils properties.Here are a few things I have discovered that might help you enjoy your diffuser. The oil and water mixture seems to be most effective (and you can smell it better) if the mix is fresh. I have tried making up twice as much as I needed, thinking that I could simply turn it on the next time I wanted to diffuse some oil. This doesn't work very well. The oil I was using was Lavender. It is very strong and easily smelled. When the mixture had sat for a day inside the diffuser it was not as strong smelling and actually smelled a bit acrid. Mix up what you think you will use in one go, you will be pleased with the results.The essential oils, two things, buy pure, medical grade, organic, concentrated oils. Anything that contains chemicals used to extract the plants natural oils; definitely disappointing, as you will smell the chemical and the desired effects of using that oil are diminished. Secondly, be sure to clean the unit between uses with clean water and liquid dish soap. The oil WILL stick to the inside edges and the bottom of the tank. Pretty soon your oils start to mix and again, the experience is less satisfying. I like to dilute DAWN dish soap in a spray bottle, keep it under the sink, spray a few good sprays into the tank, rub around with a cloth or sponge, rinse, drain and dry. Be sure to pay attention to the "Drain Side" with the arrow pointing to the top. Pour the water out of that side! If you pour the water out the other side it may enter the "Air Outlet," go into the motor and that's it, ruins the unit. I learned that the hard way! You can also run clear water through the unit as a way to clean out the area where the water is atomized if you want to. URPOWER recommends that you do this BEFORE the first use anyway.This diffuser comes with a great little plastic mixing cup with markings from 20 ml. to 150 ml. Works great for mixing up the exactamount of oil/water blend that you need. The AC adapter plugs into the bottom of the unit. When you are placing the "cap" over the tank and diffuser, match the URPOWER logo and the times up. Let the "cap" fall naturally to the bottom unit and turn slightly clockwise. When you hear the click, it's firmly in place. If the "cap" isn't on tight the unit won't work, so if the plug and everything seems ok, try re-attaching the "cap."That's it! I have gotten many months now of flawless use from this diffuser. Amazon chose it as "the best" in its own tests. That's why I purchased it. Now after using it I can definitely recommed this diffuser! Thanks for reading my review. Good Luck and have fun!

Excellent operating and functioning diffuser! Lasts for hours, displays fun colors, and provides a wonderful smelling atmosphere!

I purchased this because of the New York Time's Wirecutter recommendation as “the best essential oil diffuser.” Too bad they didn’t mention it sounds like a small propellor airplane taking off. I owned a diffuser of the exact same type (not brand) and it was almost completely silent: the only sound was the bubbling of the water inside the container. Why is this product so noisy. It would be perfect for a factory floor but not for your bedroom.

The media could not be loaded. Unit works well but definitely has some issues. First, the device was previously manufactured with a groove (shown on one photo) and pin latching but was removed because too many buyers complained that the cover was too difficult to unlatch. Unfortunately, now the cover is too susceptible to movement from being accidentally bumped or rubbed against. This can easily cause a misalignment of the arrows which causes the output port (open slot in photo) to misalign with the nebulizer (half moon shape in photo). For me, this caused the unit to shut off and water to leak out the base. Which brings me to the second issue. The power adapter connector gets plugged into the bottom of the unit. If the unit is placed somewhere that can accumulate water, there is a risk of a tripped breaker or blown fuse or worse, electrocution. I've actually considered trying to somehow attach a pin to make the latch functional.The unit has multiple colors. As shown in the video, one push of the light button sets the colors to continuously change. A second press locks in the current color. Subsequent presses rotate through light and dark hues of red, green, yellow, blue, purple, pink, and white.I use essential oils added to water that I keep in a jar. Before adding water to the device I thoroughly shake the jar to "blend" the oil and water. This seems to give a stronger scent and less residue inside the unit when empty. I accidently added water to above the fill line several times. A little above had no issues but a little too much resulted in less vapor until the level dropped. Way too much over will result in leakage.The timer has 4 settings: 60 minutes, 180 minutes, 360 minutes, and "On." The "On" setting runs the unit until the liquids are gone after which the unit shuts off (including the light). I usually get 8-9 hours using the "On" setting with the liquid at the fill line.I'd like to rate the unit higher but the lack of a latch coupled with an easily rotating cover makes misalignment an issue. Also, the power supply should either be hard wired or the connection on the unit moved or intrinsically protected against water.

In November 2024, the NYT Wirecutter rated this a "best" diffuser. I would add it's very good for a smaller space, which I have. It does what it's supposed to do, and the lighting makes it fun. Distilled water and 100% EO are recommended.
