I decided to give my house a deep clean this weekend. Using swiffer 360 duster extenders I hit a few hard to reach spots (ceiling fans, wall vents, above the fridge and on top of cabinets). It definitely made the job easier than moving a ladder around my house. Initially they lock in a lot of dust and allergens but I had to change the replaceable fiber refills about 3 times. I hesitated changing them, because I only had three and wanted them to last.  I pushed each one until they started just knocking dust on the floor vs capturing it in the fibers. The wand was very intuitive and easy to adjust. It did everything advertised such as trapping dust in every direction. I'm very satisfied with the product I just wish I didn't go through the replaceable fiber duster refills so quickly.
