Of the two pins I remembered the first already unpacked as "two-piece" out. Resending was too expensive. So I stuck the tip itself purely with "force Alleskleber" again. Let us hope that it limits the damage.
The saying "He who saves, pays twice" has again proved to be the right time. Unfortunately, this realization came too late.
When the pin is two simple plastic parts (top and headboard), which were glued into a thin sheet tubes. For quality I do not consider this product. My original ASUS pen weighs on our Soehnle kitchen scale 9 g, this here shows 0 g (in words zero!) To. Actually, I do not dare to use these fragile pin.
