I was excited to receive this book as I needed it for current classes and future practice. It came in a few days and was exactly what was advertised but at a much lower cost. The only complaint I have is that the top corner is slightly bent. I am not upset at this though because of the low cost of the book.The product looked great but unfortunately, I needed to return it. The seller is worth doing business with though!This does not seem to be a legitimate version of the DSM-5-TR published by the APA. The content appears at least similar but the font is larger, the cover color is off, the dimensions are off, and it does not have the APA authentication sticker on the back of the book. Buyer beware. I returned mine and bought a copy elsewhere.I PURCHASED THIS WITH THE EXPECTATION OF RECEIVING 10 BOOKS. I ONLY RECEIVED 1 BOOK AND IT IS COUNTERFEIT.
