The stylus has been purchased in order to use an 8-inch Windows 8.1 tablet. Here in particular, the normal desktop mode, when the symbols (eg close window) something small side. The meeting of such small objects is better than a finger, even swiping and double clicks are usually recognized. In this respect, one could give the input function 4 stars. The write function is slightly worse solved because disengages again at least for me the pen and paper out slowly rotates.
Therefore (also considering the price) in the sum of 3 stars from me.
