well i kinda think the way you have to by these kinds of things is a pyramid and not really a good salers. as far as parducts goes.... i really really like sents and the strengths. that something they have over candles and and other wax paddys. and i really really love my burnner my sister found an out of print onfor me. but the down side is , i don't really feel like the sents last nearly as long as they claim and its kinda price to burn use it up like that. i mean i guess it would be good for large space becouse the smell is strong, but i have a small space it over powering then gone,
