I am sure this is a fine product. But not for me. In the manual, it is mentioned that connecting the Visor to the keyboard may be "a little difficult." It sure was. I tried--literally for hours, and couldn't get it. I called Tech Support, and they were understanding of my trouble, they were not able to help. I was told, " . . . maybe something is wrong with the keyboard or your Visor." I returned my keyboard.
