One can thus write much more precise than with a normal, capacitive pen, because the top is not so dull. Because of the 256 pressure levels then the typeface looks really like a manuscript, ie the lines are times thicker and thinner, depending on the pressure. I like it very much. This will also be recognized when one is with the heel of your hand on the screen and this then triggers no action. Only the two buttons are placed a bit inconvenient in my view, because you can press when writing accidentally. Maybe you can avoid the by selecting the appropriate configuration. As far as I have but no longer tested.
If I had been satisfied with the Acer Switch 10, I would have kept the pen, had him so but unfortunately return.
