URPOWER Aromatherapy Essential Oil Diffuser Humidifier, 700ml Large Capacity Modern Ultrasonic Aroma Diffusers Running 20+ Hours with Adjustable Mist Mode/4 Timer Settings for Home Office Study

I have had horrible allergies this fall, and have chronic congestion and sore throats. I've tried just about everything, even the doctor, and experience no relief while taking over the counter decongestants to doctor prescribed antibiotics and nasal sprays. I find this humidifier to be very helpful in relieving some of my symptoms.It was very easy to put together, and blows a steady strong cool air mist. It can run for a very long time, about 12 hours, when placed on the 'on' setting (or you could choose the 1 hr, 3 hr, or 6 hr timers). It has an automatic shut off when it runs out of water to disperse. It has a really nice arrangement of lights and colors; you can let it transition through all the colors, or pick a color (and then decide whether you want it bright or dim), or turn off the light if you like it dark or if you want to sleep. It makes a sound similar to rain drops or a stream. It's not loud at all, but if you are extremely sensitive to noise, you might not love it; however, for the average person, I think it's very quiet. It comes with a cord to plug into the wall, and thus does not run on batteries.I'm very pleased with my purchase, and would definitely recommend this as a humidifer or diffuser. One quick tip: when taking off the lid to replace water, don't tilt the box towards the left side or all the water droplets gathered on the lid will drip out of the hole where the water diffuses (if that makes any sense). Also, make sure to follow the cleaning instructions once every 3 days and never let water sit idly in the device.

This is my second diffuser from URPower. My smaller one I keep at work on my desk, and this larger one at home.The ambient light is beautiful, nicely colored, and the transitions are smooth and gradual, versus a flashing of rapid change. I will say that the light is fairly bright for such a small unit, so just keep that in mind if you elect to put this in a bedroom and would be kept up by the light.The capacity of this unit is 700 mL to the fill line. Unfortunately the cup that comes with it is far too small to fill it, but I simply keep a 16.9 oz. Water bottle handy to fill it up. Now, adding less water will give you a stronger atomization and, therefore, more of a noticable mist. I fill mine before bed and let it run.The "throw" for essential oils from this unit isnt bad. Being that there is no fan propulsion, its unfair to expect this to fill a room with essential oils. I add 10 or so drops to a full tank, and I will say that the dispersion is pretty good.Some have complained that water drips out of the cover and "all over" when they take the lid off. This is a humidifier. It atomized water into a cool mist and projects it. That water will accumulate and condense on the surface it is propelled into. Do you want a dry humidifier? Good luck with that. Sure it does drip a little bit, so when you take the cover off just hold it over the reservoir and let it drain. It is, honestly, not a major thing.Overall, this product performs very well, looks beautiful, and does its job. So far I've had really good luck with the URPower products. My suggestion? If you're thinking of getting this unit, get it. I highly doubt you will be disappointed.

*** UPDATE 12/24/17I originally gave this product 3 stars because even though I loved it, the original item I purchased was having difficulty providing the advertised 20-hour diffusing time (the original one I received had a much shorter total run time and was shorter than advertised). However, the seller proactively contacted me and noted that they have updated their model, and he sent me the updated model at his cost. The new diffuser works perfectly! It is so good, that I just ordered another one as a gift for a friend. It covers a large space and runs for 20 hours if desired. Highly recommend for an open floor plan.11/1/17 I really love how this diffuser looks in our main living space. It is streamline and blends in with our casual and minimal decor. The diffuser itself is quiet and aesthetically pretty. It is also very easy to fill and use. I have to give it three stars though because it always leaves water in the base when it automatically turns off. I have messed with the settings and read the suggestions online and it still leaves several hours of diffusing. I was hoping it would diffuse for 10 hours on high and 20 hours on low, but instead it is more like 4 hours on high and 6 hours on low. I REALLY wanted to love this and buy 2 more for our bedrooms, but it does not make it for more than a 6 hour stretch so I will have to find different ones for nighttime.
