Lights Up pretty but not sure it actually does anything. Fairly sure if I put essential oil on anything and put it in the car it would smell good. Only seems to keep the smell for a day.
This car diffuser is amazing! It's such a pleasure to carry your favorite oils to your car for a delightful journey while running errands, road trips or for just taking it easy when traffic is crazy. I just plug it to my power slot and a blue light comes on to let me know it started working. Yes, the light does stay on but it's not a big deal, I find it pretty cool tho. It's a nice design and it's WAY better than "car fresheners" that just last for 3 days and don't do any good to your health. It comes with 3 felt pads for you to add the essential oils of your choice!. It's a good price for a product that you won't have to replace every week. Oh, the scent lasts for about 5 days then just re-apply more oil drops.
Finally a diffuser that works, I have used so many different types of diffuser in my vehicle and been very disappointed. A family member suggested this one. They use it in their vehicles and have loved it. Even when the power if the vehicle is off the diffuser still works.
Love that this does not require water. It is perfect! And even came with extra pads, something I didn't realize. Not too strong and not too weak. Thanks!
If you're a fan of essential oils and diffusing you should get this, taking your favorite oil with you in the car helps the drive to and from work or when you're about the town.
I was issued a company car in which the previous driver was a HEAVY smoker and I wanted to die driving it. I used this diffuser and some essential Oil and almost within a few days the smoke smell was gone. After about two weeks the smell was gone for the most part.
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. Very happy with the quality and price and how simple it is to use.
Wonderful product! One word of advice is to put more than 1 or 2 drops on the felt pan (don't soak it)..I place 3 or 4 (depending on the oil) and it works for days and days. Wonderful during stressful traffic.
I expected a little more out of this product. I have a sedan and as the driver I get infused but not the kids in the back seat.
Love this product! Needs to be refreshed at least once a week, but my car smells so good!
I got this diffuser and agree that the top doesn't stay on very well. More importantly, I learned the hard way not to leave it in my "cigarette lighter" all the time because, after a long weekend, I got in the car and it didn't start....the thing had slowly but surely drained my battery. I now take it out before I get out of the car.
I like this diffuser! Product arrived in a timely manner, it was packaged well. Easy to use and plug in.
I use this everyday because my job is to drive handicapped people around and it is very necessary! My car smells great and everyone is happy.
I like it! Was a gift and seems to work well. Makes car smell fresh and clean.Thanks
I love being able to determine what scent I smell in my car. I can use any essential oil I like - whatever I am in the mood for. The scent lasts a long time and is subtle, not overwhelming. I use an oil called "Joy" and I feel uplifted every time I get in my car. I have given many as gifts, too! I even love the blue light it emits.
