Details
The body is ABS plastic and metal, with a light ring and buttons on top, a mist outlet in the center and a clear base. It holds 50 ml and stands on its own base. It has five modes and a USB C port. The box holds the diffuser and one bottle of floral fragrance.
It switches on when you start the car and switches off when you stop, so it runs only while you drive. You do not need to turn it on for every trip. The five modes change how it diffuses the fragrance.
How to use
Add the included floral fragrance to the diffuser. Set it upright on a flat, stable spot in the car. Use the buttons on top to turn it on and choose one of the five modes. After that it starts and stops with the car.
Shipping and returns
Ships in 24 to 48 hours, then 6 to 9 business days in transit. Free shipping over $75. 30 days to return an unused item in its original packaging.
Safety
Keep it upright and secure so the fragrance cannot spill on the dashboard or seats, and wipe drips at once. Do not fill it while the car is moving. Keep the fragrance away from heat and open flame, and out of reach of children and pets.

Questions
Four things people ask
Which oils can I use in the car?
It depends on the piece. A diffuser with a water tank or a wood top takes a few drops of essential oil, such as the twenty House of Dusk oils in 10 ml bottles, all in the oil collection. A refill machine runs on its own refills, and the product description says which kind this one is.
How much is it, and is shipping free?
This one is $29.90, and shipping is free over $75. Below that shipping is a flat $5.90, and an unused piece in its original packaging can go back within 30 days.
How strong is the scent in a car?
A car holds a fraction of the air of a room, so any scent reads much stronger there. Start with less than you would use at home, drive with a window cracked for the first few minutes, and add from there.
Where should it go in the car?
In a cup holder, on a vent or on a flat surface where it cannot move. Anything loose in a car becomes a projectile under braking, so a piece that clips on or sits in a holder is the one to choose for daily use.
