Apparently I caught no "copy Monday" because of Velvet felt my pen leaves no black streaks or otherwise.
The brush on the opposite side works fine, but I find it a pity that it does not cover is attached. The brush may only be extended and retracted.
Also on the felt I could complain about anything, because that he should always be moist, I can not confirm.
After two cleaning my lenses it is bone dry, even though I always affixes the cover after use and put it back into the package.
Since you but according to the description moisten the glass surface before and then repeat the procedure, I'm in this regard for the time being no thoughts.
One thing I have to mention because of the felt:
He has black rub off (!). Tests the please on a white sheet of paper. You will find (hopefully) that he leaves black, circular areas.
This - I repeat it again - must be so!
This is a special powder, which binds dust particles. It is located in the cover of the felt.
This powder is always on the felt, the cover is attached and back a few times and rotated back.
Does not this method for receiving the powder, then the powder reservoir and thus the pin "empty".
If, contrary to expectations after cleaning still black powder should be located on the surfaces, so you can remove them with a brush so easy.
For this reason I can not understand the numerous negative feedback because of blackening (rubber abrasion is of course another matter ...).
