I was hesitant at first but not anymore...
I was hesitant to go with a company outside of my country since I thought it would be more difficult to get answers quickly. I also wondered about the quality of my books since I didn't want them to look cheap etc. They were very patient with me and answered all my questions quickly and fully and even took a video of my test copy so I could see every page to give approval rather than waiting to get one in the mail. I am VERY happy with the final product and the service and the price. Just know that if you don't go with air shipping you will wait about 20-30 days. I knew that going in and planned accordingly. For reference I am located in Canada.
