I used this solutions manual extensively during my Organic Chemistry class this past term. When I used this manual to help study, my exam scores were 10-15 points higher than when I did not use the book. This manual is not just an answer key like many textbooks (particularly math books) include in the back; this is a full solutions book. By this I mean the manual has the entire solution, including all the steps involved to reach the answer, for every single problem in the Smith Organic Chem (3rd edition) text. Physically speaking, the manual is an 8.5x11 B/W paperback volume about an inch thick. The color image that appears above is actually the cover of the textbook it goes with. To sum up, the content of the solution manual is great and dramatically improved my test scores, but the price is very high.
