I had used the Swiffer sweeper numerous times and was satisfied with it's effectiveness, so when I saw that Swiffer had made a duster, I decided to try it out. The first time I used the duster, I had a slight problem understanding how to adjust the handle, but once I had that figured out, I found the duster was very easy to use and even made dusting slightly fun. The duster extends and adjusts to several different angles making it easier to clean slanted surfaces and hard to reach corners. One small problem is that the disposable dusters are like the sweepers in that they get dirty quickly and have to be replaced often more than once per room being dusted. The Swiffer duster is a very handy cleaning supply that will take some strain off of housecleaning and help anyone who doesn't like dust.
Update On Oct 13, 2009: I am a bit of a cleanliness fanatic (Ok, Ok, "clean freak") So when I was required to use a feather duster to clean my work station at my job, I found myself longing for the swiffer I have at home. I really think it is the best dusting tool ever invented.
