I was so surprised how much power this sucker put out. This is an amazing diffuser. I sell and use Young Living Oils and tried it out with my Lavender YL oil pictured and it is absolutely AMAZING! It lasts a long time. I recommend this for your car or a small room like a bathroom. The directions it came with are clear and I was able to set it up easily. This diffuser also looks sleek and professional so it would look nice in a small work environment.
