As a website owner using accessibe I got tens of feedbacks from people with disablities saying they are super satisfied with that solution. Nevertheless I didn’t get any negative feedback from any person with disability who used or tried to use accessibe on my site.
That’s the only reason I feel I’m a kind of an “ambassador” here…
The only thing I know is that I couldn’t pay the rate of a comprehensive manual work on my site in order to make it accessible, and that people with disabilities are satisfied with that automated solution.
