I found a review of the mpix photo book on the website PhotographyTalk. The reviewer praised the high-quality printing and paper used in the photo book, as well as the customizable options available. They also noted that the photo book was easy to create and that the finished product looked professional. However, they did mention that the price was higher than some other photo book services, but felt that the quality justified the cost. Overall, the reviewer gave the mpix photo book a positive recommendation for those looking for a high-quality option for their photos.
