ceeniuCar Air Freshener, Smart Ultrasonic Diffuser CF12 Pro, Enlarged Spray Nozzle, Auto On/Off, Adjustable Mode, 60-Day Powerful Battery, Ambient Light, Premium Bamboo Forest Scent, Lasts 4 Months

This model is really nice. With the blue light, it gives a luxury feel to the car. Everyone has commented on how they loved the pleasant smell of the bamboo forest. Will have to see how long a bottle would last. Would definitely try other scent. Have recommended to others.

This product fell significantly short of my reasonable expectation. The quality and value for money fell well short. I don’t recommend.

I highly recommend purchasing. I have tried many different brand air fresheners but always resort back to the same 2. A white squash sent and the cassette cartridge style type you might be familiar with. But buying these becomes costly and more than $10 each and they only last a couple weeks. During the warmer weather they work well but during the winter the scent is non existent. Now this Ceeniu is a game changer. I've only been using it a couple days on auto mode and my car is always smelling good no matter the weather or if I have the aircon on or not. I will never purchase another type of air fresher again. Thank you Ceeniu.

I have mine set to auto. When I open the truck door, it kicks on. The fragrance is outstanding. I have a USB right next to the cup holder so I leave mine plugged in.
