The best thing about this item is its undeniably high quality! Im very very happy with this diffuser! I use it in my car daily and it is one powerful humidifier/diffuser! I can smell my essential oils throughout my entire car shoetly after powering it on. Its easy to use, easy to assemble and easy to clean and store. I would definitely recommend this brand of diffuser!
Bought on sale, never regretted the purchase! Just received and love it! I drive alot and I'm really going to enjoy a diffuser in my car. I like that it's adjustable (the water/diffuser portion swivels) so hopefully it would fit in any vehicle.
This is great Mini Air Purifier for Car! Beyond expectations! Quality is excellent! THANK YOU VERY MUCH!
looks beautiful, the condition is perfect! Not all things last forever. I use my car diffuser every day so I expected it to not last forever. The first one I purchased lasted almost 1 year, but I couldnt live without it so I stocked up and bought 2 more!
reasonably priced item with an excellent quality. That's a bargain! Works great 👍 Really liKe it 😁
It comes with a wick stick that you place in the middle of the diffuser. I see this lasting a while but will eventually need changed — they have one replacement, but I don’t see anywhere that you could buy another to replace. I’ve only had it for one day, so I will update in a few weeks.
Very beautiful! Arrived well packed and protected. Thanks! Easy to use, can tilt the steam in several directions so it's super versatile for different cars. I spend a lot of time in my car for work. Definitely a must during these cold winter months to keep my skin and eyes from drying out.
Just wish it diffused intermittently
I am in LOVE with this! If you are looking for an oil defuser for your car - just stop and order this one. It arrived so quickly, is bigger than i expected (this is a good thing), suuuuper easy to set up and use, and works perfectly! I love the two settings - I use the second one that sprays intermittent for aroma therapy. The stream is strong, on both settings, and with 49ml of water and half an ml of fragrance oil, the smell is perfect.
I liked how it's flexible for various plug positions. It was easy to fill and use. The container is small though. I almost missed the cute little power button on the top. Worked great. I was surprised by how much steam was coming out of it! The scent wasn't super strong, not sure if that's because of the filter or maybe I needed more essential oil. They include an extra filter, but I wasn't sure how to replace it.
Everything very well made and very well designed. recommend!
My car ride to work today was extra lovely with this diffuser going! I added about 5 drops of essential oil and it plugs right in to my cigarette lighter . You can add any oil you want and it lets out a good amount of mist. Very happy with the quality and price and how simple it is to use.
I loved this diffuser but because it sits directly under my radio in my car I can’t use it. The mist affects my touchscreen...😩
I love this! I put a few drops of my favorite essential oil blend on the wick, and it distributes through my car so strongly! I love that you can choose between constant or intermittent mode, and I have to refill about twice a week from using it during my work commute. Just a PSA, don’t use sleep support oils in this diffuser, lol!
Very fast shipping, as described. I recommend this shop. Thank you very much :)))
