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.
Love this! Really strong smell and you don't have to keep buying air filters, just add a couple drops and you're good to go!
Plug this into the “cigarette “ lighter. Put some drops on the pad. Nice fragrance comes out.
It works and does what it says it does. It does not put off a strong scent. I use it with my essential oils to relax in the car but not as a car deodorizer/ air freshener.
It works great in my truck, will get other ones for other cars and family members
After reading the other reviews I decided I would write one....I love the design ...simple and clean...the lid does come off very easily and the smell seemed to work, although faint, Just like any diffuser you have to add oils regularly ...people get into my car and always comment how good it smells and what is that...I am ordering 2 more (gifts) for friends that loved it. Yes, the top comes off but make sure you turn the lid so it screws in a bit. I load mine up with oils and it lasts for a number of days. Short or long trips don't matter. My car smells great ! I use a scent that is rather strong so there is always a scent in my car. After I bought my first one, I tried a couple of others ...I love how sleek this one is so I am ordering more!
Works great! Would buy again! Items are described and arrived quickly.
Thanks for this wonderful device! I feel good about replacing synthetic (and possibly harmful) car fresheners with essential oils... particularly during long drives.
