it cleans better than regular dusters works as good as using endust on a duster only this thing i have to thow away when it gets too dirty. replacment sheets are not sold everywhere and are expensive for people with limited budgets. they give you a new handle with every box of refills you buy unless you can find the refills seperate which is not very oftenit is cheaper to buy a duster and a can of endust which you can use over and over untill the can is empty. the duster is good for about a year.
