I'm sorry you've had a bad experience. We do spend quite a bit of time testing, and you may notice from many of our reviews that a number of users are quite happy with the product. However, there are millions and millions of PDF files in the wild and MANY MANY PDF generators, so our problem space is rather broad. I'd really like to understand the issue you are having. Could you please share the document with me at email@example.com?
Thank you for reporting the issue.
