It only produces steam. I have added 15 drops of fragrance and it only smells if you sit next to it, the surrounding area does not smell

It does its job just fine. I use genuine essential oils. I have also tried food flavors like vanilla, which dissolve in water and make the house smell amazing! It easily scents areas around 40 square meters and more, depending on the fragrance. It has a "mist" intensity setting. The LED colors can change or remain steady in the color of your choice. It has a timer to work for 1, 3, and 6 hours. I give it 4 stars because if there is about 1 cm of water left in the container, it doesn't produce steam but continues to work without shutting off. Until I find the reason, I thought there was a problem with the vaporizer.

When I realized where the oils go, it was happiness. It makes a minimal noise but it compensates with the scent it emits!
