I am vertically challenged so I use to have to carry around a step stool when I was dusting the top of pictures, door frames, ceiling corners, light fixtures. With the extender my feet can stay planted safely on the floor and still reach those high areas.
I could not live without my Swiffer dusters. Having the cloth alone is great, but having this duster with the handle is even easier. It definitely does like the commercial says, and picks up all dust like a magnet. It makes me actually want to clean because it's so easy.
I can reach places that I couldn't with any other tool. Gets those in the corner of the ceiling cobwebs every time. I'm short so it's always been hard for me to feel like I've done a good job with my cleaning. The Swiffer makes me feel like I've done the best job ever and I don't have dust coming down in my eyes.
