Lasts a long time
This particular oil diffuser lasts longer than any other one I own. It has 3 settings and will run until it's empty on the first setting. The one thing that is strange or frustrating about this particular model is that the plastic cover on the top (the part with the hole) is just set in the casing and not permanently affixed to the white casing. I had my finger on it when cleaning it and it popped out. I didn't put much pressure on it at all. It was very hard to get it to stay in there and if I'm not gentle with it, it will fall out. I can probably fix this with some super glue if it keeps happening.
Small but Mighty
So far so good. It's very small but seems to run at least six hours without replenishing the water. The top of the diffuser lights up with different colors and the steam works great for a small space.
Disappointing Prfoduct
There is no mist that is visible coming out of unit so even with premium oils you can't smell anything. Also you can't plug this unit into an electrical outlet but only into a USB port. It does not fit into my Mac.
