The software is excellent - really easy to use. I wasn#t sure whether to pay for something I'll only use a few times a year but decided to do so simply to save time searching for free software that probably wouldn't be as good. One minor niggle: I paid on my debit card and it took me back to the website, whereupon I had to pay again to gain access - not sure if I have paid twice or not. Would have been five stars other than for that.

Affordable, reliable, and flexible with changes. Could use a little more explaining to become more user friendly without having to get technical assistance all the time.
