Great passive diffuser, especially for the car
I've been using this passive diffuser for over a year. I have one in my car and one in my home. It's really nice to have in addition to my water based diffusers. It works well for small spaces like the car, and also works well for an immediate area. I'll place it right next to me in our open living room and smell it well in the immediate area, which is perfect when I'm not concerned about filling the whole space and just want to enjoy smelling my oils while relaxing or doing tasks. I've used this and the clay based diffusers from PT, and I love both kinds. The clay seem to permeate more deeply, and hold scents more strongly over time, but this lava rock alternative is still powerful and also lovely to look at. I also love it's size for my car. 👍
