Their book can rest high on their bodies leaving their hands free to hold a magnification device. You wouldn't want a new reader who has broken an arm and is casted for many weeks to lose their reading skills and fall behind the rest of the class. That might cause that student to lose is or her new found love for reading. This tragedy could affect them for life.

It's a marvelous invention and it sure makes it a pleasure and more comfortable to hold my book in a great position without wearing out my arthritic hands. Our Sanibel Public Library had it on display and patrons were permitted to take it home to test it out. This will give you an indication as to how innovative our library director is. Suggest you get in touch with other libraries.
