Although it is helpful for holding material to be copied to the computer I use it primarily to hold a magazine so that I can use my hands to eat while I read - no hands. No time wasted juggling the food and the reading material. I like that.
I give these as gifts to my daughters and best friends. The cannot stop telling me how much this saves their neck. I place a shoe box under to make taller- You can set two sheets in front of you with the clip.
