i have had this book holder for about a month and find it very useful - i use it for large and small books (largest book being a pathology textbook ~650 pagesRapid Review Pathology: With STUDENT CONSULT Online Access). the only drawback that i can think of is that if you try to write in the book while its in the stand, the stand will move, so it's not good if you want to take extensive notes in the book. for the price, (i got it for less than $7) it's a great deal.
