These actually do work!

It's nothing magical...they provide air flow between the items in the dryer. Dryer time is, of course, significantly improved with lightweight or small items but they help with larger items too like jeans and towels. It's the same principle as the plastic balls that are in the marketplace but, I found that the plastic eventually degrades from the heat and more easily get lost somewhere..I don't know..I can't find them...:O I don't think these will degrade and, there are six of them. They may compress in time but would still work then too. I like'em.
