Works very well, unfortunately, is very expensive

The stylus works 8.4 received my Samsung Galaxy Tab S.
One can thus write well (especially in the Apps a palm rest support), draw and navigate in Apps.
It is processed very clean and fits comfortably in your hand.
The automatic standby function, the service life of the supplied battery increases.
I'm very satisfied.

Supplement: In combination with the Galaxy Tab S 8.4 with the original Samsung Slim Case Cover Book you can use the latter as a palm rest, and write or draw so very convenient! There you can also increase with longer use of the stylus and the sensitivity of the touch screen in the settings of your tablet.

I would recommend the pen very. Assuming a device with sufficient capacity, which can follow the pen fast enough.
