I find the idea and visual design very well. Even the eraser on a pencil is surprisingly good. However, the supplied pencil is kept quite short already in new condition (about 2/3 of a normal pencil). Most, however, bothers me that I after a short time of use had green fingers, because the color of the pencil peeled off. Great if you're not that same notice and the documents are then full of green fingerprints. Thus, the pencil for me is absolutely unacceptable, two star there by myself for the essay with Spitzer (actually three stars, but the price just for the essay without pencil would be too expensive).
Addendum: The manufacturer has very accommodating responds to the description of the problem and made more than a substitute. It really was, this is a single problem.
