[This review was collected as part of a promotion.] Absolutely my favorite scent from Pura!!! I addicted to this scent inside my home and recently purchased a new car. So I bought the car diffuser and have Capri blue volcano on subscription. I only used this for an hour a day (to and from work total) and it makes me so happy!! Last me a little under a month based on the lowest level (which I find is plentiful scented)
