Instead of having to clock when exactly you should be refilling, the URPOWER will emit a warning sound for low power or low water, too. Even if the healing benefits or aromatherapy aren’t exactly what you’re looking for, the diffuser has some notable benefits for laymen like me who love candles. Instead of worrying if the house will burn down when you leave the room for a minute, or worse, fall asleep with one on, the diffuser eliminates all the risks with an even better end (a welcoming smell and no more colds). Not to mention that at its current price it’s about the same expense as two Yankee candles. In case you’re planning on using this in a space dedicated to letting you relax or concentrate without any disturbances, the URPOWER has a “whisper-quiet” function that won’t emit any noise, so you can work in a comfortable environment without always constantly being reminded of it. The device comes with seven different color-changing lamps for you to choose between. You can also opt just for white.Amazon More than one commenter on Amazon wrote that they’ve bought more than one for different rooms and to give to family and friends. One said that they had gone through "three different diffusers before finding this one, and it is by far the cheapest and our favorite by miles!" The only somewhat common complaint is that it’s not the easiest to twist off, but that’s because the device top locks in place so none of the essential oil spills. Once you learn how to do it, it shouldn’t be aromatherapy diffuser a problem going forward. Since ordering online always feels riskier than an in-person purchase, it’s good to know that URPOWER has earned a good reputation in customer service.
