For anyone who used to take many notes on books, this is a real revolution. I read between 2 and 3 pounds a week and my writing speed is quite insufficient to keep this pace. So I sometimes have to spend long evenings see my notes. With this pen scanner postpones everything effortlessly into a text document. The scan rate is easy to handle and can be reproduced with a reliability approaching 100% regarding the text. Amateurs Benedictine working copy, your life will be profoundly changed. I highly recommend this product.
