The design of the swiffer dusters really is much better than using rags or regular dusters.  Due to the disposable nature of it and the design, it really is able to trap dust in all the crevices without worry that it will come out on the next thing you clean.  The handle makes it easy to get the duster in hard to reach places and I've found that each duster lasts through weeks of use.  This is an overall good value and I really prefer using this as opposed to having to clean a traditional duster
