Only I can draw with the Pen better than with finger paints. This does not change even on a touchscreen.
For the pin is wonderfully suited. Within the tolerances of the display so you can achieve useful results.
The rubber hemisphere glides easily across the screen.
Unfortunately, the cap above the pens will not fit on the pin back, also is the closure of the cap is not very accurate - but ok for the price - but a star has been around for less.
With a length of just 12mm, it is also rather a shorter model.
