Very useful tool. I highly recommend it, especially for people learning languages. You write the word in Greek once and next to it you write and erase as many times the word in the foreign language you are learning so that you can easily do as many vocabulary repetitions as you want. Plus all your notes are in .pdf format and without smudges (ideal for people who see smudges and get annoyed!). Also, small and convenient, fits in bags and we also protect the environment! Oh! Goodbye to the eraser "worms" on the desk and floor :) I am very satisfied!

It helps me a lot to easily convert my notes into electronic format and archive them. Unfortunately, the OCR doesn't have great success with my own handwriting. So, I keep them as an image.
