This document holder is a good tool. It does not take up a lot of room on your desk. The only thing I would change about it would be some kind of slide that could be attached to it that would move up & down the page so it is easier to follow lines of work.
I needed a Horizontal Copy Holder for entering orders from a measure sheet. I put a rubber band around the bottom so the opening isn't as wide and lean it against my monitor riser. I added a thin piece of cardboard so I can write on sheets when needed. The magnets are quite strong and hold a few pages at a time (haven't tried more than 3). I am very happy with this product! My little froggy friend keeps it from sliding into my keyboard.
