I just got my order of this and the Journal of Impossible Things from WhoNA, and I love this air freshener! It's a little spinning TARDIS (as advertised) that sticks to your dash. The vibration of the car movement makes it rotate ever so slightly and, really, it is working very well making my car smell better (I occassionally have to haul garbage a few miles in my trunk), though I'd equate the scent to urinal cake (which is not a bad smell in itself, a bit like lemon).
I'm tempted to buy a second for possible future use.
