Today Bernd Jaeger published an interesting review on rosenblut.org about the Jot Pro. He tried to focus on the precision of the Jot and compared it with another stylus. It is obvious that the Jot with its innovative disc wins this by far.
We would like to add that an even better response when placing the Jot on, e.g., a tablet and a higher precision as well comes with the Jot Mini. It has got another disc which results in just that extra in precision.
