I bought to accompany a windows 8 tablet devoid of electromagnetic slab (techno n-trig, wacom, ...)
It's not nearly as powerful as a real stylus with wacom technology to draw, but the stylus is comfortable and pleasing to the utiliser.L'utilisant Android or Windows, it works as a simple capacitive style but mine is much finer and pleasing to my hood avis.Le holds well when it is pushed properly.
Bluetooth can be used to vary the thickness and must relate to the hand detection in some applications not supported ... I know non-application in the Apple universe.
The problem is that there is sometimes a delay between the pen tip and clicked area, but it is much more accurate than when using my finger.
This fine point pen simulates the size of the finger by the onboard electronics and therefore it is not as accurate as an electronic stylus wacom type.
Otherwise I would have put the score of 4 if the accuracy was better and the rating of 5 if the additional functions operated under different OS (Windows and Android)
