Diser Stylus now has a narrow, well-operated top and through the Bluetooth connectivity also works the Handball protection better than any other solution. Once the pin is coupled with Penultima you can rest your hand to write easily on the iPad without worrying that you leave unintended lines and characters.
However, one needs a bit of practice to the pen well and quickly be able to make on the iPad notes, the surface of the iPad happens to be smooth and he has Stylus thus less resistance than a ball point pen on paper, which is used to, but after a few days ago I can not tell the difference anymore.
From all around me a buy rating, despite the high price!
