My claims it was not enough.
On my tablet, the sensitivity of the stylus was too low to write and write without dropouts I wanted with this stylus.
Processing, feeling in his hand and the idea of replaceable tip I think is great! (Hence 2 stars)
But for all their love, a new stylus must be recognized by a commercially available touch screen but 100%.
From the aforementioned reason, I have the pen also sent back.
Now I use again a cheaper Stylus, which, although less pretty and somewhat inferior haptics has, but reasonable writes.
