This book is a paradox in of itself. It uses such simple and basic language, as if to train one in the most foundational form of English grammar and yet has no more than a few sentences doing justice to the subject matter. It's oversimplified speech but lacking descriptions make this book such a snore and useless piece of writing!
This product is satisfactory for anything less than 1.5 inch thickness. Its unable to hold up many of my university books, not even textbooks, but paperback small books.
Its okay in the sense that if I had a photocopied course package, I could use this for that purpose.
