I am constantly on the go, and I always over look small details, so that is why I didnt realize my Febreze Car Clip was empty, and still smells incredible. That normally wouldnt be surprising, if I hadnt bought the little car air freshener over an entire year ago. Yes, I bought my Febreze Car Clip last year in March of 2013. I remember this because I bought my mini van in February of 2013. So this little clip has sat clipped to my air vent, empty, probably since April, possibly May even. And my mini van still smells like I just bought a brand new Car Clip from Febreze. Amazing product!!!
