Use more oil
This is a very beautiful diffuser. However, at first, I could barely smell the scent at all and considering the price I actually thought about returning it. I have a very large open room and was using approx. 10-12 drops of oil. The scent was not nearly strong enough. I tried it in a smaller room and it did better. I have now discover that in my larger open area room it does very well if I use 15-20 drops of oil. That is a lot of oil and it may depend on the brand and quality of the oil. But either way, using more oil is better than having to use two diffusers in the same room.
