On the subject Scharzer filming. If it is a manufacturing defect I find the 1-star Bewertgungen of the product in order. I could also imagine, for example, that the product has been stored incorrectly and the cleaning surface is moist or wet. Maintains it clumped and then lubricates the surface - this is certainly not. Basically, I would replace the product, and then writing a review. Would be purposeful if the review does not relate to a manufacturing defect. Since this is apparently not an isolated case, I have been understanding.
If an operator error sees a little different. However Hama should perhaps mitliefern a small leaflet which explains the correct handling of the pen and the "common mistakes" in the form of a "FAQ" lists.
The brush of any cap has not interfere in the least. In my opinion, it is intended for the removal of dust and dirt. Because it needs no cap.
From my side, a strong buy recommendation.
