This product is great for the car but you need to buy the oils to diffuse separately. The humidifing portion is great.
I really liked this little defuser. Depending on how much oil you put in and the scent it’s pleasant to smell. I used too much oil to start. But I’ve got it down now. Goes through water fast and I live in a very cold city so it did freeze. But I really like it.
This little air diffuser is great to have in your car. It beats having a regular car air freshener. I add scents that go with the season and it diffuses great. I keep a water bottle in my car so that when it has no water I can refill. There are reviews that says the diffuser stops working or there is a red light but the light is just saying that it’s off. Press the button once it turns green which means continuous . Twice it turns purple which means intermediate so every 8 seconds it will spray for a few seconds then turn off and three times it turns red which means off.
Absolutely amazing, 100% recommend for everyone!
Such a low priced mini air purifier is truly a bargain. Thanks to the seller!
I love it, even when I wasn't feeling good I put in Eucalyptus oil to breath better and it did the trick, however, watch out for some oils with strong odor that might be over powerful inside the car/SUV. With no oils and I want that humidity in the air it does the trick. Glad I bought 2 of them one for me and one for a gift. And they told me they love it too. Better quality than expected, Shipping was quite fast!
It has a touch sensor with three different settings “continuous,” “intervals,” and “off.” We were able to use it for about 3 hours before it emptied. It works so. well. and reaches the entire car.
There's not much to say. This has worked for me so far exactly as advertised. As for some people saying 'no scent' that hasn't been my experience. Maybe try using a different oil. I don't know. My only "issue" is that the on/off button, it's not clear from the lights when the unit is on/off, and really only know if I see vapor. Not the end of the world, especially for twelve bucks. I'm hoping it continues to work as I've seen a number of reviews here that says it just stops working at any given point. But as of now, after about a dozen uses, it's all good.
arrived in time and there are no defects. Goods meet the expectations.
I love my aromatherapy air humidifier! It makes my car smell great and right now during the winter season we’re not constantly shocking ourselves due to static electricity! Lol I use it every time we’ in the car and we drive an hour one way every Sunday to visit family and it lasts the whole way there. I fill it back up with distilled water and oils and drive all the way home.
thanks a bunch! It's just a great, solid, dependable product. Everyone who rides in my car loves it and wants one. I Lyft in DC and constantly get compliments about the smell of the essential oil from the diffuser and how cool it looks.
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!
