Books arrived in fantasic shape.
Format: Paperback, Format: Paperback
I was worried about making the purchase due to other people having problems with miscut books and glued pages. I ordered the set of three and they are all in great shape. No miscuts or glued pages. Every page seems to be printed legibly. I'm very happy with my purchase. I didn't see any recent reviews so I thought this may help some of those hesitant to buy.

Good so far.
Format: Paperback
I will be using these heavily in a month or two, I ordered them because they were on sale so I will come back and edit once I actually read the material, use the glossary, online tools, etc.
However from out of the box? All the books are in perfect condition, no sticking pages like other reviews. I will say if you can afford the hardcover version with the labs? Get those.
From touching them once or twice so far, this book will not stand up to constant use. It's a really flimsy type.. not even sure if it's paper? It feels like plastic paper.
I will also add that that study guide book is F A T . I wish they would have split it into two. I bet the hardcover is gigantic because mine looks like the biggest dictionary you've seen, and I know the cover page which is almost exactly like the pages? Will be ruined once it starts being used consistently.
