The rubber tip is a (hollow) rubber sleeve that rests softly on the display and with some pressure, we work a finger. For drawing on the tablet as a pin is almost a must, because that is more intuitive than a finger use and results in the more considerable results.
+ Works equally well with and without screen protector
+ Soft rubber is gentle on the display, is easy to clean and does not attract dirt
+ Ballpoint pen writes wonderful (better than my other coolies, and I have a few) - even a replacement cartridge is
+ Compact form factor fits perfectly to the phone or tablet, and fits comfortably in your hand
o the peak might be a little harder for my taste and it would be nice to have to press less firm. However, it may be that the pen would not work in the (capacitive) display - that would be a shortcoming, which is due to the display.
