They sent me the wrong book and won't rectify the issue. Actually I cannot get them to reply anymore. I submitted an unfavorable review and it never made it to their website; ironically only 5 star reviews are on the website. You will have no recourse if something goes wrong (like in my case). You would lose/waste your money (and the time you spend emailing them). They are in Malaysia (I did not know that until I received the Fede shipping email with tracking) following which I had a bad feeling about the interaction (only to have those feelings proven correct!).
