KNFB reader

I recently purchased the KNFB reader ap for my I phone. I love it. It makes reading so much easier. And it really works. I payed 100 euros for it but it was really the best hundred euro I ever spent. Last night I tried it out and I was able to read all of my mail hassle free. I was even able to read the label on my cerial box. It really is brilliant. Has anyone gotten it or used it? If you have what do you think? Were you impressed? Did it live up to your expectations? Are you glad you bought it?
