That should possibly know

You can replace the rubber tip of the integrated in Note 10.1 S-Pen against the white in the Stylus.

At the beginning of the stylus from the Note 10.1 was not recognized. I disabled the setting> S-Pen> Energy Saver, then it went. Alternatively, you can remove the built-in Pen but I thought that was pointless.

I find the stylus great, it fits comfortably in the hand and does not slip due to its matte finish.
In white, it is significantly cheaper than in black, and also much fancier :)
