I have purchased a crystal diffuser for all of my cars! I just ordered another for my daughter's car, she just got her own car. It diffuses the oils in the winter when the heat is turned in and in the summer when the car gets warm inside, I replenish the oils ever couple months and they seem to last about that long. Great stocking stuffer !!
It doesn't fit Corolla vents— the clip part is twice as long/deep than it needs to be, but luckily I was able to kinda force it onto the bottom of one of my vents. Other than that works great! Tried it out with 5 drops of Mountain Air and is almost too strong! I suggest starting with the recommended 3 drops and add more as needed.
Love the idea of diffusing in the car without having to plug anything in. I plan to use this every day to help me relax before going to work. As a teacher I’m feeling a lot of anxiety about this school year. Will definitely be using some relaxing and immune boosting oils!
The different colors were beautiful. It fits perfectly in my car vents and doesnt look bulky.
I haven't tried these diffusers yet as I have one I had before switching to plant therapy that in using till it dies. But I've read reviews about the smell not lasting long. Just remember these are natural essential oils that you are putting in these diffusers and some scents last longer then others. Some are top, middle and bottom notes. And we also become what some refer to as nose blind, but the benefits are still there for awhile. I love all the research and time Plant therapy puts into their products.
Driving can be stressful at times, Im glad that I can diffuse as needed without having to use water. I add about ten drops every couple of days, I usually try to use oils that are calming and about to expire.
I bought this for my wife's car. Scent is not too strong, so it's nice.
It’s okay but the smell doesn’t last very long. It’s pretty easy to use and clips easily onto the vent.
We are loving this carfresh diffuser for the car. You can put whatever your heart desires in it and make it as strong as you like. Simple and easy!!
Overall I like it. I’ve only used it in the summer and the smell is not overpowering. I’m curious to see how the heat setting affects it.
I was a little concerned about the car diffusers but once I tried I got pretty sympathetic and enjoyed a lot. Especially in the mornings, I like the orange sweet smell. My favorite
It took me ages to decide to buy this and I’m so glad I did. I love having it on in the car when driving and it’s nice that I can easily take it off to bring inside out of the heat. I’ve only had this a few weeks and have been just using strong smells but I’ve been very happy with them and they’ve lasted a couple of days. I’ve also only used it with AC so still have to see how it works with hot air coming through. Either way I’m so happy with it and thin it’s definitely worth it for this price especially.
I love that I can put my own scent in this. Very convenient.
I love the idea of having EOs in my car instead of chemical scents and I love this diffuser! I actually bought two as gifts for other people. My only issue is that my car is older and it's the 1% where the vent slots are too small to slide the diffuser in as is. I removed the provided clamp and replaced it with bobby pins. It works but it's not as solid a clamp as the original one would have been. But I still love it
Scent is subtle but I know I can still benefit from properties. When I first get in the car, I can smell it. When I first got the product, I couldn't figure out how to open it to get the stick out... It is obviously magnetic... :-)
