I just tried a new product called Glad Expressions Oil Diffuser. The scent I selected is "Lavender & Juniper Berry". I placed it in my guest bathroom and it provides a nice continuous scent to both the bathroom and the surrounding area.
I also like the look of the diffuser. It fits in nicely with my decor. I was very pleasantly surprised that the scent was not too over powering.
It is a bit pricey when you buy the starter set, but they do sell refills that are more cost effective. I recommend you give it a try! I participated as a BzzAgent and received a free Glad Expressions Oil Diffuser as part of the campaign. I am sharing my own honest opinion.
