The pin slides easily across the screen (without protective film) and allows a very precise input.
For occasional manuscripts quite suitable, who often relies on this, however, should look more towards a "adonitol".
The "Solo" is to me compared to the "duo" a little too easy, however, offers the possibility to protect the head by the cap.
The workmanship is very high quality, convinced the analogue use of the "Duo" as a ballpoint pen (black).
Anyone looking for a solid all-rounder, who was not to be deterred by the price - the investment is worthwhile.
