The wiper is divided into three in respect to the material. On the lower surface is the non-woven fabric, which absorbs the residues from the whiteboard marker. Here, the quality of the marker is critical. The cheaper models require sträkeren of force. The high end pens can be removed relatively easily by double Drüber Wipe.
A bit annoying for my taste is the size of the logo in the middle of the product. It would be desirable for me personally a more subtle application of the brand name.
