Bath and Body Works Flowers Scented Oil diffuser Review

I tried the Bath and Body Works Wall Flowers for the first time around the holidays when they were on sale.  The person working there raved about them and I bit the bullet and bought a starter kit with extra refills.  I'm so disappointed in them.  First of all, the refills don't last a very long time and they are more expensive than the Glade or Air Wick air fresheners I can buy at Target.  Personally, I don't find them to be any better than the grocery store type of air fresheners, either. Secondly,  I can smell them if they are in a bathroom but they're useless in any other room in my home.  I absolutely can't smell them at all.  What a waste of money.
