If you leave it for too long, the quality deteriorates. I have it on an automatic on/off switch to work specific hours, not 24/7. After 2 months, the color of the scent inside has changed

I have it at a very low intensity and it smells strongly in the room, especially in the living room. But this scent is overwhelming. There is no reason to increase the intensity, but if I did, I wouldn't be able to stand it in the living room. It's suffocating. If there was a lower intensity option, it would be better. I have it plugged in relatively close to me and it bothers me. I put it in a more distant outlet and it still becomes annoying. The space smells strongly and my family is bothered by it. I can't leave it on for many hours. It doesn't work at all for a small space. I won't choose it again. I just chose it because there were only three options at the supermarket. I was wondering how it would smell when I bought it and how much space it would cover, and in the end, it not only smells but it's overwhelming. Of course, these are personal preferences. When I smell it outside the outlet, the scent seems nice, but when it's plugged in, it changes and becomes heavy. I didn't like it.
* After a few days of use, and simply because I paid for it, I regret not getting the classic lavender and choosing this one. It's unbearable. I wasted six euros. If I leave it on for a while, I feel restless and I open the windows to freshen up the space. At the lowest intensity, it's tolerable. It does do the job, but choose a different scent! Unless all scents of this type are like this. I don't know.
