The pros: - Superb gliding sensation, even compared to Wacom that I also have but which suddenly does not serve me. - The pressure management - The LED that changes color depending on the selected color (depends on the applications that support it) - The Bluetooth 4 that guarantee a long service life - The good grip - The best software support it (but not necessarily with all the options: eg recognition of the palm does not work with Sketchbook Pro, which is a shame because this is we gain comfort and precision) except ArtRage. - Comes with a battery
The -: - Looks more like a marker pen pencil - The tip is wide, which requires some practice to gain precision
Accuracy, I have a iPad 4. Although it is not 100% perfect, it's currently the most pleasant and most functional stylus on the iPad. A tip when you draw or write with the stylus, disable the "Multitasking Gestures" (icon "Setting" menu "General") at the risk of having behavior annoying especially if you put the palm on the screen with apps that allow it.
