"I am very happy with the software. It does exactly what I need it to do and it is configurable to my preferences. I really don't have anything negative to say about it. It is more affordably priced than other software I looked at and does the job - just what I hope I can say of software. Yes I had used CompareRite in the past, although not recently. I had no difficulty with the transition"
