When I was about to bring the device to my husband, so it only the 2nd time took out of the package, was thrown out a small metal pin, the upper and lower parts hold together and the whole thing fell apart more or less in its individual parts. But we had it assembled quickly and pushed the pen again. Now it stops again. My husband is additionally fix it. I mean, that was an unfortunate accident, just bad luck that makes device as stated otherwise a stable impression, but I did not want to leave this event still unmentioned.
