How it knows halt.

Who bought the dust magnet, was supposed to have a few feather dusters are already included in the package. The refill kit is similarly composed of 3 x 20 piece of it.
The dusting is so especially in typical "paint" products (TV, display cabinets, ...) a breeze.
I like to use it to get rid of in a very short time ~ 80-90% of the visible dust.
Caution in humid areas: Here let it dry until everything (eg bath & Co..). Otherwise, loud Staubklümpchen that no longer can be with the magnetic dust sweep readily form. Then you have to help out with water, cloth and dry cloth, which increases the cost significantly.

Otherwise, highly recommended if you are satisfied with the dust magnet. The price per Wedel is not too high through the refill kit.
