I buy a lot of air fresheners for my home because some of my relatives smoke and I like to cook with exotic spices. I decided to try Forever Fragrant fresh sticks since their claim is that it lasts for 2 years. To my mind it could potentially save me a lot of money. The positive points are it does seem to remove unwanted odors specially in my kitchen and bathroom. The scent is clean and not overpowering (I got the vanilla variant). Unfortunately it does not last as long as advertised. It lasted about 3 months before it stopped working. If I do the math I'll probably save more money buying Febreze.
