Just starting using this today for a very thick book. I love it! Great price and the tabs that hold the pages are very sturdy. I recommend this copy holder.
I wanted a stand to hold my typing while I'm working in the computer. This stand fits the bill perfectly. It's sturdy has two clips at the bottom to stabilize the pages of an open book and folds to a small article for storage. Well worth the price!
It is sturdy and holds the book up right. I found that turning the pages was easy. but because I had to go back and forth between sections of a 700 page book that the corners of the pages became a little worn. The book was rented.
