Of the scents I have tried at Reed Diffusers dot com, the scents do last.
However, keep in mind it takes a while for the scent to make it's way UP the reed and to get into the air.
I have found it takes a few days for the scent to become evident. If you are looking for a "whole house" scent solution, this might not work for you.
Within the room, the scent is evident. And, after a few days I catch a slight scent, but it is not a strong throw.
Someone mentioned Pier 1 scents and I have found them nice as well.
I like diffusers because they are no fuss. No soot, no flame, and they are subtle -- nothing to plug in or worry about.
