i like how fast it works and that you can set it to turn off in two hours. If you forget , it automatically turns off in two hours. The scents i chose may not be as strong as I'd like but i can still smell an aroma after its off for hours. Also, i chose this over all others because it can be plugged in. i don't want to mess with a battery or a remote. i have too many remotes in my house. It's easy to move from room, if needed. i really like it so far but it is ugly!

Nice looking diffuser that ALMOST does it well.

Easy to use, easy to clean, easy to move. These are well made diffusers and work really well in a smaller space like a bedroom, bathroom,kitchen or office. More than that and they need a second unit to keep up. A typical living room or family room are too much for the amount these put out. I plan to buy one or two more for other spaces in the house.

One Fill Lasts Hours!

I truly enjoy this ultrasonic aroma oil diffuser by Mainstays. I bought a six-pack of essential oils to go with this purchase and my home smells wonderful. So far, there are no issues with this device in the short time I've owned it. You will enjoy the ambiance of a dampened light throughout your day with the convenience of push-buttons to control the unit at your convenience and to suit your preferences. I'd say each full tank of water with essential oil drops runs for about 6 hours in my estimation. If you enjoy fragrances for your space and are tired of breaking the bank constantly buying things that peter out after a week or two and don't last anywhere near as long as they claim on the package, then you can't go wrong with giving this unit a try.
