to tap ok. to not draw.

it is certainly unfair, a product difficult to assess when the competitors it (mostly) also can nciht better.
But when I bought the part, were the implications me unaware.
so I want to prepare other köufer it.

none of the available "stylusse" really is, writing or drawing.
the tip must have a large druchmesser, like a finger. otherwise they do not work.
You also have to impress them relatively strongly. otherwise they do not work.

So if you want screen simply keep its clean, which is certainly well served by something.
If you want more, you should get yourself a tablet with wakomsensor.
as there are pins for that work well.
