See it in action
Put a few drops of my Sauvage in and my car literally smells like me now. My coworker asked what cologne I was wearing — I wasn't wearing any. It was the diffuser.

Latest Reviews
My car used to smell like fast food and gym bags. Filled this with my cologne and now it smells like a luxury car dealership. Best $50 I've spent.
Finally a car freshener that doesn't give me a headache. Used my own essential oils instead of those chemical pine trees. Highly recommend.
Was skeptical at first but this actually works. Filled it with my favorite perfume and I love it. Battery still going after 3 weeks.
Honestly didn't expect much but my coworker asked what cologne I had on and it was just this thing in my car vent. Ordering a second one for my truck.
I drive for Uber and passengers keep asking what cologne I'm wearing. It's not cologne, it's this thing on my vent. Game changer.
