I use the book holder when I am having breakfast alone and want to read. It works great except for the tabs at the bottom that hold the pages in place; they keep coming off and it is difficult to get them back in the slots correctly. One has disappeared so I have to prop the page open with my cell phone or other object.
Great for using textbooks that are related to my digital art field which often require that you're doing something on the computer and reading the book. Love the portability and holds up my medium sized book well. Not sure about a large heavy book yet but haven't tried. Great product great for doing something while you're reading (like school related)
I use the product for presenting my program using a 3 ring notebook. It fits in my notebook along with my program stands strong on a table to flip pages and looks good while doing it. Works better than an easel for me.
I was looking for womething that would hold books open hold one sheet at a time upright while I was typing. I also wanted something to be at "eye-level" so I would not have to keep looking up and down etc. This is exactly what I wanted/needed.
