I bought this book holder for our music stand at Church. We have a lot of small and large music books we move back-and-forth during our Divine Liturgy. We were always having to hold the pages open on the current book for others (or ourselves) in order to sing. This holder fits perfectly on the music stand--in collapsed form--and the two page holders at the bottom work exactly like we need them to in order to keep the pages from flipping on us or the book from closing. The two little tabs that keep the pages in place are really clever; they have a bit of stiffness which is perfect in order to push them down turn the page then push them back into position. Definitely recommend it for anyone using a music stand who experiences the same kind of issues with music books/sheet music.
I have recently started back to school and my regular copy stand wasn't big enough to hold my textbooks open. The adjustability of this one is great! It also helps that this on folds up and even has 3 holes in it where you can put it in your binder and take it with you.
I open the stand as far back as it will go (last notch) and use a rubber band/paper clip combo to keep the legs connected then turn the product backwards so the "lip" is away and the "lift" is foreward. Then I slide the netbook on so it is held in place by the "lip". The result is an air space under the netbook PLUS the front is lifted and provides a wrist rest while I type PLUS I can pick everything up and set it on a rug or the bedspread or pillow or even carry it around conveniently if I have to leave the rocking chair or bed or kitchen table. This reversed direction (see photo) positions the keys at an optimal angle to prevent carpel (doesn't require me to lift up the fingers to reach the qwerty or digits or FN rows). Will consider getting another just in case but it's a tuff little worker. Slips into soft-side case to offer armor to the netbook. I'd give it a 5 if the last notch would stay latched which I'd also need for book reading. But paperclip and rubber band do the trick. I have worked using this combo for 6-8 hours without any hand or arm fatigue. In the rocking chair I run the mouse on the chair arm. Out on the steps in the sun I run the mouse on my pant legs. Or I can just unplug the mouse. This bookholder is FAR better on a plane than the dropdown table that the kid in front of you is constantly jiggling. It's the best portable table I've ever had the pleasure of using. I might even use it as a book reader but for that purpose it doesn't look like it will hold a book open without a major rubber band across the book and around the back. But since I can read PDFs...
I use this project for typing up study notes for school. It makes it so easy to type up highlights and excerpts from my textbook. The only complaint I have is that the adjustable page markers become detached easily; but they are easily re-attached and they do hold the book steady. This is a great buy and makes my life a lot easier!
