Just a couple drops and you’re in heaven. This is by far the best way to go as far as aroma therapy. I was using a candle type and it was just a pain in the butt and I was always afraid of a fire especially last at night if I fell asleep, this one has no hot parts and is absolutely safe. This Amir is much easier to use and I believe the oil lasts longer than the candle type. I use it as a night light, it shines a beautiful, subdued colored light that’s very attractive. I definitely feel better in the morning. Highly recommended.
