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... :-)
I love the look of this little diffuser and the fact that I can change it whenever I like. My only complaint is that the smell doesn't last long enough.
Works very well and my car smells amazing!
I love this little car diffuser. Easy to use with the magnetic clip to change out the gem piece. Love the scent it gives off!
I've been using this car diffuser since first offered them. Moved it to my new vehicle. Excellent passive diffuser that allows me to chose from my large collection of essential oils and change up what I diffuse. I love my woodsy scents, so that is what I frequently use, but occasionally I do something floral or citrus.
Very convenient and easy to use. Nice being able to bring nature into my ride.
I love how the look and the good quality of the diffuser
I really love how this works in my car! I use lavender in it and relaxes me when I am commuting to work and doesn't disrupt the heat or ac in my car!
LOVE this spin on car diffusers. The crystals are cute and the scents last quite a long period of time. Will be buying these as gifts 🎁.
