A slightly queasy feeling you already, if one operates his baby, so to speak open-heart, especially as the surface of the pin formally drawn on the sensor, which has first been chasing me a proper fright.

A cleaning process has initially not enough for me - had a total of 3 x stamp - but the sensor was actually extremely dusty. And even if the result does not bring 100% Cleanliness - 2.3 grains keep all Abtupfversuchen bravely stood - there's almost a perfect score from me, because the sensor is compared to previously re pretty virgin and the traces of 6 years within 30 minutes and removed with no detectable degradation. That is the money then it worth, I think. Nevertheless there's 1 point deduction for the price, because in spite of everything expertise are 40 euros for a plastic pen of about 5 grams, a little package, a little sticky notes block and an English-Chinese instructions a little too much.
