This pen scratched your screen

Please save yourself the trouble with this pen, although it has a nice writing experience but what
uses when your screen is scratched? In another review is posted, you may the
Pin only in the context of a film used - even this advice I followed.
The film, I again removed after just one week and almost no use of the pen, the film
is full of impressions of the congregation, makes no sense at all.

Unfortunately, I've used the pen before without foil a few times, which I regret now.
I do not understand how such a pin can be sold when he scratched the display (?).
I can still clearly recognize a few letters on the display, and just as I
mentioned low usage. Just imagine if I had the pen "properly" used!
Now I'm trying to remove these small scratches - annoying!

Please be warned, in English-speaking forums, other users describe the same problem.

UPDATE 08/09/12:

Manufacturer contacted, of course has one of each debt and refers to test results
that would refute the scratching. Why then have so many buyers this problem?
Look at this, please also the US side at Amazon (amazon.com) and check the 1-star reviews on this article, numerous
Notes with "Scratches on display" should be warning enough.
Have now bought the Boxwave Ever touch with fiber mesh tip (no classic rubber tip) and am very satisfied, one must now fear no longer be displayed. I use the pen daily to capture notes (App recommendation: Notes Plus) and am convinced of this combination.
