I love the Bath and Body Works Wallflower fragrance bulbs! There are so many different scent options that almost everyone should be able to find one that they like. There are also a variety of different looking plugins so there is one for almost any style of room your putting it in. One bulb generally lasts about a month or two, and they make your entire room smell wonderful,but not over powering. My favorite scents are watermelon lemonade for summertime and mahogany teak wood for winter, but there are many other that I also like. They can be a little pricey to but individually, but there normally is some kind of promotion where you can buy more and save.
