Directions did not work for me.so I left it upside down overnight in the cup holder and then the car smelled fantastic!!! It's very pretty yet to heavy for the mirror. So I hung it off the passenger visor and it looks and smells amazing!!! The good thing with the visor location when I flip the visor up it moves the jar and the scent continues on .i knotted it short it so it sways just a little . I was worried the heavy glass could hit the window. When you view the jar from the outside of the car it look really pretty and sparkles nicely. So it's simple and pretty.
