Feedback from initial users of the KNFB Reader.

"The playing field has been equalized with the assistance of the KNFB reader. I feel that the scanner will make me more employable, besides assisting me to do my work independently."
Review Author Hope Hein
"I was planning to have someone read me the serial number from the battery in my laptop; however, the person could not seem to read the number the same way twice. It wasn't easy -- tiny little print on the end of a long skinny box, but I got it with the K-NFBR. The beauty of this is that the K-NFB Reader, obviously not designed for anything remotely similar to this task, outperformed a sighted reader."
Review Author Anonymous
"I really didn't know what to expect, when I got it. But, from the first picture I ever took, I was extremely impressed. [...] the Reader is so handy and portable, it’s really extremely useful."
Review Author Cynthia Handel
"I just finished sorting today's mail. What a great feeling I have to be able to accomplish this seemingly trivial task. I didn't have to interrupt my son or daughter, I didn't have to wait for a pair of eyes, and my wife does not have to spend time sorting. [...] As my students would say, ‘The K-NFB Reader rocks!"
