I bought the cleaning brush to my keyboard to get rid of dust. After the first use I realized that the dust was indeed removed almost completely - but instead, were everywhere in the "cracks" the fine brush hairs. Apparently there is a mass product of poor quality (Far East goods?) ... The product is not worth a penny unfortunately. Unsuitable even as a promotional gift. Too bad. I have since seen better quality from PEARL Versandhaus expected.
