Query: F.A. Davi's Practice Guide for the Radiography Examination

This product is worthless. I really don't recomend to buy it. I just bought this book because it offered a CD-ROM wich does not work with my operating system (XP). I opened from the package because it's labeled that works with XP, but it does not, it get frozen my computer as soon as it reaches 61% of installation. If you are going to prepeare for your radiographic examination the books you have used during the program will help yuo out a lot. On the other hand I could not return this product to Amazon for refund because I opened it and I tried to contact these people (F.A. Davi's publisher) trhough the internet and then they are just around the bushes solving nothing. This product has to be updated and they have to offer a better product for what you are paying for.
