The quality of the provision of this pen is stirring: the seizure of my daily 8-10 A4 pages of notes takes me much less time than before. Note that to arrive at a suitable interpretation of my notes, I must ensure that my writing and treat late afternoon (fatigue) or when time is short, the recognition rate decreases sharply. However, the configuration of the interface allows to juxtapose the notes and the result decrypted by the software, so that corrections are fast. In summary, I am satisfied with my purchase: to run, I think that efforts on the quality of my writing will help me to earn even more time.
