I am very short so most tables are higher on me. Using this product I found that the highest position was still too far back for me to see properly (without a glare). Small books aren't held as securely as possible.
I have a "book pillow" that I like but it is "soft"! I stumbled onto this on the clearance shelf by accident and was thrilled because I had wanted something like it but did not know anybody made it.
When buying this I was worried if just pages not bound in a book would work. It works great. No slipping and I have stacked as little as 5 pages at a time on it.
This is a good book holder. You can adjust the angle the book is held at. I really liked the fact that it folds to a very compact shape and has no bulges. The flips that hold the book open are the only weak point as they tend to come loss and you need to make sure not to lose them. That said they are easily placed back and it is like new again. I use it in my tutoring so both I and the student can see the question. It folds nicely and fits in an already crowded brief case. I actually bought one for myself to use t home.
